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.

Same CRC was always reported if the memory region was in the cache...

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.
