bios/spiflash: fix write/ erase, add write from sdcard and range erase

Lukas F. Hartmann cb2a789008 bios/spiflash: bring back write and erase, add write from sdcard file cmd 
When shipping MNT RKX7, I pre-flash the SPI flash with a LiteX bitfile
for testing. cmd_spiflash had regressed because of changed SPIFLASH defines
and didn't offer the write functions anymore. This commit fixes that, and
adds convenience functions:

- flash_erase_range <offset> <count (bytes)>
- flash_from_sdcard <filename>

The latter reuses some boot code to copy the contents of the specified
file from the boot FAT partition on the SD card to SPI flash (i.e.
a bitstream).

Lukas F. Hartmann 118dd6ed08 liblitespi/spiflash: add erase and write functions 
The code is based on norbert thiel's comment https://github.com/litex-hub/litespi/issues/52
But edited to work with W25Q128JVS flash used in MNT RKX7.

Florent Kermarrec b367c27191 integration/soc/zynq: Revert previous commit (incorrect), re-enable CSR decode on Zynq7000/MP and add check/error when SoCBusHandler has more than one Region and one of them has its decoder disabled. 
This will prevent silent errors and means offset needs to be added in Software.
 2023-04-12 19:54:01 +02:00
Florent Kermarrec f44ff2bac4 integration/soc/SoCBusHandler: Force interconnect to Crossbar when at least one region has the decoder disabled. 
See https://github.com/enjoy-digital/litex/issues/1665 since optimizations on Shared Interconnect can't be used with
disabled decoder.

dasdgw b1e02ebcfa soc/software: fix i2c_write 
commit 3fa3080e introduced an additional address length paramater to
i2c_write to support non 8bit memory addresses.
But the parameter wasn't added to the call of i2c_write in i2c_send_init_cmds.

This commit fixes the issue by adding the address length parameter to
the call of i2c_write.
