* mx25: Clean up lowlevel_initBenoît Thébaudeau2012-10-15-31/+3
| | | | | | | | | | | | | | | Clean up mx25 lowlevel_init: - Add comments. - Do not use write32 repeatedly with the same value in order not to increase code size. - Make register values configurable. - Use macro parameters with default values instead of literal constants. - Use defined macros instead of duplicating code.

* KARO TX25: Fix NAND Flash R/W cycle timesBenoît Thébaudeau2012-09-23-0/+8
| | | | | | | | | | | | | | | | | 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 accesses. This patch fixes this issue by setting the NFC clock to the highest frequency complying to the 25-ns NF R/W cycle times specification, i.e. 33.25 MHz.

* Add support for KARO TX25 boardJohn Rigby2010-03-07-0/+131
This is an i.MX25 base board with only NAND so it uses nand_spl to boot. Signed-off-by: John Rigby <jcrigby@gmail.com> Tune configuration, add support for (redundant) environment in NAND.
