$litex_sim --ram-init=demo.bin
Press Esc during the LiteX boot.

The CrossoverUART was in fact a particular UART connected to a second UART. Being able
to have access to multiple UARTs over a Bridge can be useful for several purposes, ex:
SoC0 --> UART0 + JTAGBone + litex_term bridge --bridge-name=UART0
SoC1 --> UART1 +--> SoC --> UARTBone --> LiteX-Server + litex_term bridge --bridge-name=UART1
SoC2 --> UART2 + EtherBone + litex_term bridge --bridge-name=UART2

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:

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.
