[U-Boot] [PATCH] KARO TX25: Fix NAND Flash R/W cycle times

2012-08-08 Thread Benoît Thébaudeau
The NAND Flash of the KARO TX25 board is a Samsung K9F1G08U0B with 25-ns R/W cycle times. However, the NFC clock for this board was set to 66.5 MHz, so using the NFC driver in symmetric mode (i.e. 1 NFC clock cycle = 1 NF R/W cycle) resulted in NF R/W cycle times of 15 ns, hence corrupted NF access
