[U-Boot] [PATCH 0/3] Add raw read support and use it in pxa3xx NAND driver

2018-10-11 Thread Miquel Raynal
When using 2kiB-pages NAND chips requesting an 8-bit strength ECC, the layout used is a bit particular and it happens that the ECC engine tries to correct uncorrectable errors on empty pages, producing bitflips. To avoid such situation, raw read support is added to the pxa3xx_nand driver, and then
