> Subject: [PATCH] at91sam9x5: for ROM base address (bugfix for nand ECC)
Argh! After a lot of editing, the subject line is wrong.
fix ROM base address (bugfix for nand ECC)
Anyways, let me add this detail. The current code considers the
case where dev_request_mem_region() fails.
host->pmecc_rom_base = dev_request_mem_region(dev, 3);
if (!host->pmecc_rom_base) {
[...]
What it does in "[...]" is creating the tables with proper math.. I
tried to skip the request_mem_region() above and ECC works perfectly,
with the software-generated table.
So I wonder whether it makes sense to just remove the declaration of
the ROM are memory-region-3 for NAND, and just use the software-built
tables.
This wouldn't void the previous patch: the ROM address is wrong
as defined, for all CPU types that fall under "at91sam9x5" (I checked
the 5 data sheets: G15, G35, X25, G25, X35).
thanks
