Same issue as ENGR00321137, commit 3695635. GIS module need total 3M+3M+1.5M+1.5M=9M video memory. and sys reserved 16M memory for malloc.

2016-02-17MLK-11718-2: mtd: nand: change the BCH layout setting for large oob NANDHan Xu
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>

2016-02-17MLK-11408-2 imx: mx7d: Isolate 26 IP resources to domain 0 for A coreYe.Li
In current design, if any peripheral was assigned to both A7 and M4, it will receive ipg_stop or ipg_wait when any of the 2 platforms enter low power mode. We will have a risk that, if A7 enter wait, M4 enter stop, peripheral will have chance to get ipg_stop and ipg_wait asserted same time. There are 26 peripherals impacted by this IC issue: SIM2(sim2/emvsim2) SIM1(sim1/emvsim1) UART1/UART2/UART3/UART4/UART5/UART6/UART7 SAI1/SAI2/SAI3 WDOG1/WDOG2/WDOG3/WDOG4 GPT1/GPT2/GPT3/GPT4 PWM1/PWM2/PWM3/PWM4 ENET1/ENET2 Software Workaround: The solution is set M4 to a different domain with A core. So the peripherals are not shared by them. This way requires the uboot implemented the RDC driver and set the 26 IPs above to domain 0 only. CM4 image will set the M4 to domain 1 only. This patch enables the CONFIG_MXC_RDC for mx7d SABRESD board and ARM2 boards, and setup the 26 IP resources to domain 0. Signed-off-by: Ye.Li <B37916@freescale.com>

For USB boot, eg, mfgtool programming case, some laptops/pcs may not work properly if the board do not disconnect until linux kernel usb driver initialization process, finishes the ROM code connection at u-boot can fix this problem, and this was the original work flow when mfgtool flow was introduced at u-boot.

2016-02-17MLK-11238 imx: mx7d fix usdhc pad settingsPeng Fan
To CD/VSELECT/RST, should use same pad settings with USDHC_PAD_CTRL, because default NO_PAD_CTRL's settings is 100K Pull-Down. But, we need pull-up for CD/VSELECT/RST. Also some board provides external pull-down/up, we'd better use internal pull-up for these pad settings. To mx7d_12x12_lpddr3_arm2: If no card plugged in, "mmc dev 1" will show "Card did not respond to voltage select". After apply this patch, it will show "MMC: no card present". To mx7dsabresd: Alougth without this patch, if no card plugged in sd1, still correct msg "MMC: no card present", anyway we'd better use pull-up. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>
