[U-Boot] Does U-boot supports Spansion S29GL512P NOR Flash?

Hi Stefan,

>> Right. Most likely you just need to tune the chip select timing registers
And of course the size of the CS.
What mean by size of CS? Which file I should check for timing register for
S29GL512P?
>> BTW: You might also need to configure a bigger TLB entry for the FLASH
now that you use a bigger FLASH chip.
Does uboot support one single TLB entry for 64MB size. At pesent I have
configured 4 TLB entries, each 16MB.
