[U-Boot] [PATCH RFT 0/3] spi-nor: spi-nor-ids: Fix 4 Byte addressing for n25q256 and n25q512*

[Eugeniy Paltsev]

Hi Vignesh,

I've check this patches on top of 31e086e460f.
The read/write/erase seems to work. 

However, as I can see 'sf protect lock' doesn't work - it finish successfully but the area remains unlocked.
As I remember It worked with old u-boot spi-nor code, but I need to check it.

Subject: [PATCH RFT 0/3] spi-nor: spi-nor-ids: Fix 4 Byte addressing for n25q256 and n25q512*

This series removes SPI_NOR_4B_OPCODES flags from legacy variants of
n25q256* and n25q512* and adds entries for newer variants of those
flashes that support 4 Byte opcodes.

I don't have the flash devices. So its only compile tested.

Ashish, Simon,

I would greatly appreciate if you could test these patches and make sure
4 Byte opcodes are being used. (Probably by enabling/adding prints to
cmd->opcode in spi_mem_exec_op() in drivers/spi/spi-mem.c

Euginey,

Could you test this series on top of latest u-boot master and confirm
that your test cases still work?

Regards
Vignesh
