I am working with a board that has 2 CFI-compliant Spansion S29JL064H flash
memory devices. Each device is 64 Megabit (8 M x 8-bit / 4M x 16-bit) in size.
The two flash memory devices are connected in "parallel", effectively doubling
the word size while maintaining the total number of sectors, i.e.,
Single Device
-------------------
Bank Megabits Sector Sizes
1 8 Mb 8 8Kbyte / 4Kword
15 64Kbyte / 32Kword
2 24Mb 48 64Kbyte/ 32Kword
3 24Mb 48 64Kbyte/ 32Kword
4 8 Mb 15 64Kbyte / 32Kword
8 8Kbyte / 4Kword
Two devices connected in "parallel"
--------------------------------------------------------------------
Bank Megabits Sector Sizes
1 16 Mb 8 16Kbyte / 8Kword
15 128Kbyte / 64Kword
2 48Mb 48 128Kbyte/ 64Kword
3 48Mb 48 128Kbyte/ 64Kword
4 16Mb 15 128Kbyte / 64Kword
8 16Kbyte / 8Kword
Question:
Should I expect u-boot's common CFI driver work with this configuration?
