Efinix: suport spi width for passive loading
2024-02-05 12:43:30 +01:00
Sylvain Munaut 3127e504d3 soc/integration: Allow 0x400 CSR paging
It's a convenient way to get more CSR locations without changing
the whole address space layout (i.e. more space for CSR).

It still leaves 256 full 32b registers in each location which
I've never encountered a device even coming close to this, so
it should be fairly safe to do.

This doesn't change the default, just allow the user to select it.

Andrew Dennison f81c940e7b litex/build/efinix: add binary output
This is the file required for passive SPI loading.

Andrew Dennison d9f006e123 litex/build/efinix: add spi_width
Doesn't seem needed for Trion but probably essential for Titanium?

Merge pull request #1881 from motec-research/spiflash_fixes
Spiflash fixes for issues exposed by sys_clk = 200MHz and L2 cache

Andrew Dennison fc85fdd178 build/openfpgaloader: support args with '-'
many openfpgaloader args have a name with '-' as per normal convention.

This kwarg now works: file_type="raw"

Andrew Dennison de594e44c9 software/bios/cmds: fix crc command with L2 cache
Same CRC was always reported if the memory region was in the cache...
Noticed when manually testing spiflash divisor.

Andrew Dennison 3a890a077b software/liblitespi/spiflash: fix clk_freq tuning with L2 cache
Correct CRC was always calculated, regardless of divisor, as the
test flash block was in the L2 cache. This resulted in the minimum
divisor being used and incorrect flash reads with 200MHz sys_clock.

Andrew Dennison 51c3cb3552 soc/add_spi_flash: default clk_freq to 20MHz
This is safer than defaulting to sys_clock / 2 if sys_clock > 100MHz
clk_freq tuning will result in a faster clock if supported by hardware.
