2019-07-19ARCH: imx: Call sata_remove() not on imx6 duallite/solo boardsLudwig Zenz
For a single binary approach for imx6 quad/dual/duallite/solo it is necessary to enable CONFIG_SATA for quad/dual. On the other hand on imx6 duallite/sole SATA is not available. Therefore sata_remove() is skipped according to a blacklist scheme. Adding further imx derivates is probably not recessary as they are usually not pin-compatible and therefore a different board with its own configuration.

2019-07-19spl: imx6: Let spl_boot_device return USDHC1 or USDHC2Adam Ford
Currently, when the spl_boot_device checks the boot device, it will only return MMC1 when it's either sd or eMMC regardless of whether or not it's MMC1 or MMC2. This is a problem when booting from MMC2 if MMC isn't being manually configured like in the DM_SPL case with SPL_OF_CONTROL. This patch will check the register and return either MMC1 or MMC2.

2019-07-19i.MX6: nand: add nandbcb command for imxShyam Saini
Writing/updating boot image in nand device is not straight forward in i.MX6 platform and it requires boot control block(BCB) to be configured. It becomes difficult to use uboot 'nand' command to write BCB since it requires platform specific attributes need to be taken care of. It is even difficult to use existing msx-nand.c driver by incorporating BCB attributes like mxs_dma_desc does because it requires change in mtd and nand command. So, cmd_nandbcb implemented in arch/arm/mach-imx BCB contains two data structures, Firmware Configuration Block(FCB) and Discovered Bad Block Table(DBBT). FCB has nand timings, DBBT search area, page address of firmware. On summary, nandbcb update will - erase the entire partition - create BCB by creating 2 FCB/DBBT block followed by 1 FW block based on partition size and erasesize. - fill FCB/DBBT structures - write FW/SPL on FW1 - write FCB/DBBT in first 2 blocks for nand boot, up on reset bootrom look for FCB structure in first block's if FCB found the nand timings are loaded for further reads. once FCB read done, DTTB will load and finally firmware will be loaded which is boot image. Refer section "NAND Boot" from doc/imx/common/imx6.txt for more usage information.

2019-06-27mx6sl: hab: Fix pu_irom_mmu_enabled addressBreno Matheus Lima
According to hab.c code we have to notify the ROM code if the MMU is enabled or not. This is achieved by setting the "pu_irom_mmu_enabled" to 0x1. The current address in hab.c code is wrong for i.MX6SL, according to ROM map file the correct address is 0x00901c60. As we are writing in the wrong address the ROM code is not flushing the caches when needed, and the following HAB event is observed in certain scenarios: --------- HAB Event 1 ----------------- event data: 0xdb 0x00 0x14 0x41 0x33 0x18 0xc0 0x00 0xca 0x00 0x0c 0x00 0x01 0xc5 0x00 0x00 0x00 0x00 0x07 0xe4 STS = HAB_FAILURE (0x33) RSN = HAB_INV_SIGNATURE (0x18) CTX = HAB_CTX_COMMAND (0xC0) ENG = HAB_ENG_ANY (0x00) Update MX6SL_PU_IROM_MMU_EN_VAR to address this issue.
