[U-Boot] [PATCH] Common: SPL: spl_nand: Fixed debug correct NAND ECC type.

In case of #define DEBUG 1 (fordebugging SPL). A bug in spl_nand_load_image() will be triggered, because it prints using hw ecc regardless of soft ecc configurations and initializations. Signed-off-by: Ahmed Samir --- common/spl/spl_nand.c | 4 1 file changed, 4

[U-Boot] [PATCH] cmd/nand.c: Remove unnecessarily repeated step

Getting the current NAND device is already done once as part of nand command. Therefore, repeating this step as part of the sub-commands is unnecessary. Signed-off-by: Ahmed Samir Khalil <engkhali...@gmail.com> --- cmd/nand.c | 6 -- 1 file changed, 6 deletions(-) diff --git a/cmd/

[U-Boot] [PATCH] cmd/nand.c: Debug additional helpful NAND info

While dealing with large chips (e.g. page: 4KB, OOB:224), we found it helpful to get these additional NAND info by enabling the DEBUG macro instead of full tracing every time and consuming time. Especially about the currently in use scheme for testing & development. Signed-off-by: Ahmed S

[U-Boot] [PATCH 5/5] mtd: spi_flash: preserve Spansion's original value during reboot

Spansion flash has QEB in the same status register as well. Therefore, preserve the original values while rebooting. Otherwise, some SPI controllers may be unable to access the flash correctly e.g. receive garbage bytes instead. Signed-off-by: Ahmed S. Khalil ---
