[U-Boot] ramtron f-ram

[Ran Shalit]

Hello,

I use the spi interfaces with more then one flash in the U-Boot. Actually I
use one spi fram(ramtron) and one spi flash (stmicro).
I first thought that configuring both flags is just what I need:
CONFIG_SPI_FLASH_STMICRO
CONFIG_SPI_FLASH_RAMTRON
But since the ramtron implementation change the value of IDCODE_CONT_LEN, I
will get that this constant (IDCODE_CONT_LEN)
is OK for one flash but wrong in the other. I had no choice but to make
changes in the code for my case. just wandered if there is
really such limitation (that I cannot use ramtron & other spi flash
together).
Best Regards,
Ran
