Stephane Gourichon f71275a3f1 Show speeds in bytes per second. 
Forcing megabytes per second for everyone does not make sense.
Showing bytes per second allows to distinguish between low performance and a performance measurement bug.
Anyway previous code claims speeds were in MiB/s, they were not, actually MB/s.

Stephane Gourichon 48638f936b Fix SoC CPU crash on minimal variants on call to flush_cpu_dcache(). 
Generated soc.h says for example

but code tester for CONFIG_CPU_VARIANT_MIN not MINIMAL.
Attempted to run instruction unknown to this CPU, most likely cause of hang.

Stephane Gourichon e47f84ea79 Unconditionally ask dfu-util to "Issue USB Reset signalling once we're finished". 
Some host machines need it.
If issuing -R always does not cause any trouble, then do it.

Gabriel Somlo c77da3a8bc RFC: json2dts: set CPU clock-frequency and SoC bus-frequency 
FIXME: timebase-frequency isn't to be used as the raw CPU clock, so
on vexriscv we might want to re-evaluate also setting *that* to the
`CONFIG_CLOCK_FREQUENCY`. Decide whether to keep the SoC's
`bus-frequency` cell, or whether to go with the CPU's `clock-frequency`
only.

bunnie 7b42992383 add <memoryRegions> outer tag to series of <memoryRegion> for future proofing 2020-09-29 14:11:55 +08:00
bunnie 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>
            <size>0x00020000</size>
        </memoryRegion>
        <memoryRegion>
            <name>VEXRISCV_DEBUG</name>
            <baseAddress>0xEFFF0000</baseAddress>
            <size>0x00000100</size>
        </memoryRegion>
        <memoryRegion>
            <name>CSR</name>
            <baseAddress>0xF0000000</baseAddress>
            <size>0x00040000</size>
        </memoryRegion>

Merge pull request #652 from gsomlo/gls-sdcard-clocking 
RFC: proper way to set sdcard clock?
 2020-09-22 21:52:13 +02:00
Gabriel Somlo 8e7596d330 liblitesdcard/sdcard.c: ensure effective sdcard clock is <= requested 
With the way the clock divider is currently calculated, it is
possible for the effective sdcard clock to end up *higher* than
the requested `clk_freq` value.

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
frequency.
