0e7d8219ea soc/cores/gpio: Simplify GPIOIn IRQ, make polarity configurable and also add optional IRQ to GPIOTristate.
Ex of instance:
from litex.soc.cores import gpio
gpio_in_pads = Signal(16)
self.submodules.gpio_in = gpio.GPIOIn(gpio_in_pads, with_irq=True)
self.add_csr("gpio_in")

fc83a9281a interconnect/csr: remove address wrapping within a CSRBank.
To minimize logic, decoding inside a CSRBank to limited to the CSRs inside
the bank and could wraps since partially decoded:

For example, accessing SoCController on addresses still on the CSRBank defined
for real CSRs produced:

litex> mem_read 0x82000000 128
Memory dump:
0x82000000  00 00 00 00 78 56 34 12 00 00 00 00 00 00 00 00  ....xV4.........

This is generally not an issue on most of the systems, but it could confuse user
or produce un-wanted behaviour when bus data-width converter are used.

With this change, the address is fully decoded, which removes the address wrapping:

7ce5aef428 soc/cores/led: add add_pwm method to allow adjusting brightness dynamically (or not).
LedChaser without PWM:

self.submodules.leds = LedChaser(
    pads         = platform.request_all("user_led"),
    sys_clk_freq = sys_clk_freq)
self.add_csr("leds")

Add PWM to it (with default values: 50% duty cycle):
self.leds.add_pwm()

Add PWM with custom default values (25% duty cycle here):
self.leds.add_pwm(default_width=128, default_period=1024)

Then adjust brightness dynamically from the BIOS or your software:

$cat csr.csv:
csr_register,leds_out,0x82003000,1,rw
csr_register,leds_pwm_enable,0x82003004,1,rw
csr_register,leds_pwm_width,0x82003008,1,rw
csr_register,leds_pwm_period,0x8200300c,1,rw

Set PWM to 0%:
$mem_write 0x82003008 0

Set PWM to 25%:
$mem_write 0x82003008 256

Set PWM to 50%:
$mem_write 0x82003008 512

Set PWM to 75%:
$mem_write 0x82003008 768

Set PWM to 100%:
$mem_write 0x82003008 1024

You can also only use default values and disable CSR is dynamic configuration is not
required (with_csr=False) or adjust PWM period if want to use a specific PWM period
in your system.

927fd675bc sdclk: additional halving to prevent clock going "too fast"
When the system/bus clock frequency is an exact power-of-2 multiple of
the desired sdcard frequency, we can drive the latter at the "maximum"
speed via the "perfect" divider. That sometimes turns out too fast, so
in order to be conservative, we double the divider, thus halving the
resulting sdclock.

b03f46ffec soc: increase sdcard data/cmd timeout (from default 10e-3)
This allows the Linux driver in single-block mode (cmd17-only) to
operate solidly, without running into timeouts from LiteSDCard FSMs.

FIXME: multi-block (cmd18) transfers still time out, so revisit this
after some additional debugging.

ead12df21b soc/cores/gpio: review/simplify #810.
Use irqs dict and "rise", "fall" strings instead of Enums:

Ex: pads=Signal(8), irqs={}                    : 8-bit Input, No IRQ.
    pads=Signal(8), irqs={0: "rise", 7: "fall"}: 8-bit Input, rising IRQ on 0, falling IRQ on 1.

Also simplify the logic.

8e4202ced1 software/bios/readline: Fix warnings if char is signed
When building with --cpu-type=mor1kx:

    litex/soc/software/bios/readline.c: In function 'readline':
    litex/soc/software/bios/readline.c:271:3: warning: case label value exceeds maximum value for type [-Wswitch-outside-range]

      281 |   case DEL:
	  |   ^~~~

The C standard does not specify the signedness of "char", hence this
depends on the implementation.  On e.g. RISC-V, "char" is unsigned, but
on OpenRISC, it is signed.

Fix this by making the "ichar" variable explicitly unsigned.

The default value of "master_doc" was changed from "contents" to "index"
in Sphinx v2[1].  As the LiteX doc system creates "index.rst", it thus
fails to build with Sphinx v1.x.

Explicitly configure "master_doc" to "index", to make it work with all
versions of Sphinx, regardless of the default.

7b3737f531 cpu/vexriscv_smp: Make sbt failures fatal
When using a non-default VexRiscv cluster config, the netlist for that
config needs to be generated.  This requires sbt to be installed.
If sbt is missing, an error message is printed:

This message may easily be lost in the noise, as the build continues, and fails
later with:

    ERROR: Can't open input file `litex/pythondata-cpu-vexriscv-smp/pythondata_cpu_vexriscv_smp/verilog/VexRiscvLitexSmpCluster_Cc1_Iw32Is4096Iy1_Dw32Ds4096Dy1_Ood_Wm.v' for reading: No such file or directory

      printf("CRC32: %08x", crc32((unsigned char *)addr, length));
				  ^

Fix this by using the appropriate types (uintptr_t and size_t) for
memory addresses and sizes, which are defined to 32-bit or 64-bit,
depending on the platform.

Note that the specified length must still be smaller than 4 GiB on
64-bit, or it will be truncated, as the crc32() function is currently
limited to a 32-bit size anyway.

857ef69b3f software/bios/boot: Fix cast to pointer from integer of different size warnings
On 64-bit:

    litex/soc/software/bios/boot.c: In function 'serialboot':
    litex/soc/software/bios/boot.c:216:20: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
	 writepointer = (char *) get_uint32(&frame.payload[0]);
			^

When casting from a 32-bit integer to a pointer (32-bit or 64-bit,
depending on the platform), an intermediate cast to "uintptr_t" should
be used to avoid warnings like the above.

Note that using a 32-bit integer is OK, even on 64-bit, as this is
specified by the boot protocol.

thus causes subtle misbehavings.

61895bef37 rocket: Fix UB due to optimised away DFFs
As both clock and async reset for the debug DFFs were 0, and there was
no initial value on them, they were being validly optimised away by
newer Yosys versions to 1'bx which was propagating into and breaking the
core.

This fixes the problem by tying the async resets to the CPU reset
signal.

This way, user scripts can be use RemoteClient (communicating with the Server that has

Using RemoteClient is more generic but can be slower (due to the Etherbone encoding between
the client and server). On fixed configuration using CommXY directly can then be faster
and also avoid manual opening of the server.

90d71ec247 Add initial interrupt support for Microwatt in LiteX
There is a conflict between the LiteX way of doing things and the POWER
way of handling interrupt tables.  LiteX expects to be able to put a ROM
at address 0 and load an application into RAM at a higher address; POWER
is architected to jump to exception handlers at 0x100...0x1000.

As a result of this, we have taken the approach of placing generic exception
handler entry / exit routines into ROM, and reserving a single pointer in
SRAM to determine the C ISR handler location.  If no application is loaded,
this pointer is set to the BIOS ROM ISR.  When an application loads, before
reenabling interrupts, it needs to set __rom_isr_address to the address of
the application's ISR, otherwise the BIOS ROM ISR will continue to be used.

Tested to operate with the built-in UART in IRQ mode, both in BIOS and in
loaded RAM application.

4a94bb78f6 add memory regions to soc.svd
svd2rust does not recognize memory regions, but we'd like to
make an access crate for Rust that does.

This patch adds memory regions to soc.svd using the "vendorExtensions"
tag, as specified in https://www.keil.com/pack/doc/cmsis/SVD/html/svd_Format_pg.html

The vendorExtensions is added as a block after the Peripherals level, and has a format
like this:

```xml
        <memoryRegion>
            <name>SRAM</name>
            <baseAddress>0x10000000</baseAddress>

Calculate the divider starting with the `CONFIG_CLOCK_FREQUENCY/clk_freq`
ratio which is then rounded up to the nearest power-of-two, ensuring
that the resulting, effective clock frequency is <= to the requested

d86d20671e bios/sdcard: use (512 byte) blocks as the smallest addressable data unit
In liblitesdcard/sdcard.c, replace s/sector/block/ as the 512 byte sized
unit of data transfer to/from the sdcard.

In bios/cmds/cmd_litesdcard.c, do NOT multiply block numbers by 512,
allowing any "block" (a.k.a. "sector") on the sdcard to be addressed for
testing.

Before this patch, user-input "block numbers" were multiplied by 512 and
passed into sdcard_[read|write]() as "sector numbers", with the sdcard
logic internally treating these as 512-byte sized addressable units on
the card. This resulted in only every 512'th 512-byte sized "sector" being
accessible from the bios command line.

d783e86ff6 add a pipe register to relax an async_default timing path
there is an async reset signal going to a FIFO
that can't be false_path'd because its timing is important
to making sure that the burst FIFO is reset to zero when
a miss happens in the burst cache. Unfortunately as designs
get full, the routability of this signal becomes difficult
and drives up the compile time and reduces quality of results.

There is enough time in the design to insert a single pipe stage
to alleviate the timing somewhat. This commit adds that register.

e0b2b8153f liblitesdcard/sdcard: read sdcard response only when needed
Instead of reading the 128 byte sdcard response after each operation,
read it only during debugging and/or when it's necessary (to retrieve
the relative card address, rca).

We no longer need a global sdcard_response array, and refactor the
various retrieval and reporting functions to contain a local buffer
for that purpose, only if/when necessary.

00629c45b0 interconnect/csr: add CSR registers ordering support.
The original CSR registers ordering (big: MSB on lower addresses) is not convenient
when the SoC is interfaced with a real OS (for example as a PCIe add-on board or
with a CPU running Linux).

With this, the original ordering is kept as default (big), but it can now be switched
to little to avoid software workarounds in drivers and should probably be in the future
the default for PCIe/Linux SoCs.

df3428be07 liblitesdcard/sdcard: (temporarily) slow down SDCARD_CLK_FREQ to 25MHz
Rocket's DMA slave interface (and/or internal routing) currently
appears unable to route DMA writes from LiteSDCard at frequencies
above 25MHz (as tested on nexys4ddr, with Rocket, at 75MHz main
system clock frequency).

d8161e5a86 integration/soc: make DMA slave region cover (at least) the lower 4GB
Assuming we currently support a 32-bit (4GB) physical address space,
ensure that the dma_bus slave covers the entire range, covering any
possible layout of the LiteX SoC memory map (e.g., rocket has MMIO
in a wide range of registers located below 2GB, and DRAM starting at
the 2GB mark, needing DMA accesses to be routed appropriately for the
entire 4GB physical address range).

70eae5cbf9 interconnect/wishbone: increase WB address width to 31
This is needed to support memory regions up to 4GB in size (currently
limited to 2GB, or 0x8000_0000).

FIXME: CI complains about assertions re. axi_lite.address_width in
       relationship to len(wishbone.adr) and wishbone_adr_shift, which
       seems to be a problem on the 32bit (vexriscv?) CPU used for CI,
       but seems to work fine on Rocket.
