* MLK-12102 mmc: fsl: introduce wp_enablePeng Fan2016-03-04-4/+8
| | | | | | | | | | | | | | | | | Introudce wp_enable. If want to check WPSPL, then in board code, need to set wp_enable to 1. Take i.MX6UL for example, to some boards, they do not use WP singal, so they does not configure USDHC1_WP_SELECT_INPUT, and its default value is 0(GPIO1_IO02). However GPIO1_IO02 is muxed for i2c usage and SION bit set. So USDHC controller can always get wp signal and WPSPL shows write protect and blocks driver continuing. This is not what we want to see, so add wp_enable, and if set to 0, just omit the WPSPL checking and this does not effect normal working of usdhc controller.

A enet2_en pin is added for isolating enet2 signals with EPDC, we also add support for enet2. 3. pin6 of 74LV output is changed for CSI PWDN. Set output to high to power down it. This patch also tries to get the board id and apply changes according with it. Since current RevB board does not burn GP1 fuse for board id, we have to check the TO rev instead even it is not very exact. Will update this if any new way implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Android's tool chain enable the -mandroid at default. This option will enable the -fpic, which cause uboot compilation failure: " LD u-boot u-boot contains unexpected relocations: R_ARM_ABS32 R_ARM_RELATIVE " In my testcase, arm-linux-androideabi-gcc-4.9 internally enables '-fpic', so when compiling code, there will be relocation entries using type R_ARM_GOT_BREL and .got section. When linking all the built-in.o using ld, there will be R_ARM_ABS32 relocation entry and .got section in the final u-boot elf image. This can not be handled by u-boot, since u-boot only expects R_ARM_RELATIVE relocation entry. arm-poky-linux-gnueabi-gcc-4.9 default does not enable '-fpic', so there is not .got section and R_ARM_GOT_BREL in built-in.o. And in the final u-boot elf image, all relocation entries are R_ARM_RELATIVE. we can pass '-fno-pic' to xxx-gcc to disable pic. whether the toolchain internally enables or disables pic, '-fno-pic' can work well.

* MLK-11718-2: mtd: nand: change the BCH layout setting for large oob NANDHan Xu2015-10-15-23/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | The cod change updated the NAND driver BCH ECC layout algorithm to support large oob size NAND chips(oob > 1024 bytes). Current implementation requires each chunk size larger than oob size so the bad block marker (BBM) can be guaranteed located in data chunk. The ECC layout always using the unbalanced layout(Ecc for both meta and Data0 chunk), but for the NAND chips with oob larger than 1k, the driver cannot support because BCH doesn’t support GF 15 for 2K chunk. The change keeps the data chunk no larger than 1k and adjust the ECC strength or ECC layout to locate the BBM in data chunk. General idea for large oob NAND chips is 1.Try all ECC strength from the minimum value required by NAND spec to the maximum one that works, any ECC makes the BBM locate in data chunk can be chosen. 2.If none of them works, using separate ECC for meta, which will add one extra ecc with the same ECC strength as other data chunks. This extra ECC can guarantee BBM located in data chunk, of course, we need to check if oob can afford it. Signed-off-by: Han Xu <b45815@freescale.com>
