Hi Jagan,
Up to now, I didn't find the 4-Byte addressing mode support.
Do you know if anybody have schedule to add it?
if no, could you please apply this patch, due to as I have said when do the
warm
boot up, the SPI flash will be kept in 4-Byte addressing mode that kernel
driver set,
while t
Hello Jagannadha and Siva,
Do you have any idea for if there should be a shift upon the flash size?
If yes, why there isn't one when initializing the BAR read/write commands?

Hi Jagannadha,
See Siva's comments inline and For the DUAL spi flash memories, do you have any

Hi Zhejiang/Jagan,
I think it would be good to extend this further to support 4-byte addressing in
u-boot also.
This would be based on the driver, We can get the data that whether the
controller supports 4-byte or not from the driver level(through slave struct)
and enable 4 byte addressing here
From: Hou Zhiqiang
For more than 16MiB SPI flash chips, there are 3-Byte and 4-Byte address
mode, and only the 3-Byte address mode is supported in U-Boot so far.
So, reset the SPI flash to 3-Byte address mode in probe to ensure the SPI
flash work correctly, because it may has been set to 4-Byte a
20 matches
