Konrad Beckmann 39d144626b Fix build issue where sdram_leveling is not found
4f76656 rewrote how sdram_leveling() was called, leading
to linking problems for targets with sdram but with
write leveling disabled, e.g. ulx3s.

Florent Kermarrec 4f76656018 software/liblitedram: simplify vtc/hardware/software controls.
- move vtc control to sdram_software_control_on/off.
- remove sdram_calibration (duplicate of sdram_leveling).
- be sure to call sdram_software_control_on/off before all litedram bios commands.

Florent Kermarrec 6d07f01f5b tools/litex_client/RemoteClient: allow use without local csr.csv file.
In some case, we just want to access MMAP manually without having the csr.csv file:
wb = RemoteClient()
wb.open()
wb.read(0x40000000)
wb.close()

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.
