* MLK-12001 MMC:USDHC: Clear DLL_CTRL delay line settings at driver initYe.Li2015-12-14-0/+3
| | | | | | | | | | | | Clear DLL_CTRL delay line settings at USDHC initialization to eliminate the pre-settings from boot rom. U-boot should re-init the USDHC not reply on the value set by boot from. On MX6DL, the ROM has set the default delay line(DLLCTRL) to 0x1000021, when eMMC works on DDR mode in kernel, it will possibly cause data CRC errors. Even u-boot always use eMMC in SDR mode, for safety sake, it is better to clear it too. Signed-off-by: Ye.Li <B37916@freescale.com>

* MLK-11946 arm: config: disable pic when compiling codePeng Fan2015-12-03-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-11823 USB:gadget Fix USB port interface issue in ci_udc driverYe.Li2015-11-04-1/+1
| | | | | | | | | | | | | The ci_udc driver tries to use the ULPI interface for the USB OTG controller, but this type is not supported by all i.MX6 and i.MX7 platforms. When setting to ULPI, other platforms except the 6UL refuse the settings and keep default value. But on 6UL, the PTW bit of PORTSC1 register which is documented as RO can change. This cause the interface setting problem with USB PHY. Fix the issue by removing the ULPI setting for i.MX6 and i.MX7. All will use default UTMI setting. Signed-off-by: Ye.Li <B37916@freescale.com>

* 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>

* MLK-11408-2 imx: mx7d: Isolate 26 IP resources to domain 0 for A coreYe.Li2015-08-25-0/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
