2017-08-31disk: part: align buffer so it can be used with DMA enabled driversStefan Agner
When using ISO partitions with a DMA enabled block device driver reading the ISO partition leads to unaligned DMA operations: CACHE: Misaligned operation at range [bffb7da8, bffb85a8] Align the buffer to make sure we pass a buffer which works for DMA operations.

2017-09-01colibri_imx7: carve out PMD aligned amount of memoryStefan Agner
If the Cortex-M4 is running we carve out 1MiB of memory for rpmsg communication and/or the firmware running from DDR. On the Colibri iMX7D this area is in the middle of its 512MiB of memory. Linux seems not to handle the sparse memory area well and shows only the first 254MiB of memory as available. Enabling highmem seems to work around this issue. However, enabling highmem is not ideal since memory from the highmem area is more restricted then lowmem. Aligning the carved out memory to ARM Linux' PMD (page middle directory) size of 2MiB seem to allow allocating all available memory as lowmem. Hence increase the carveout region to 2MiB.

We have two commands to change the bootmode fuses: mfgr_fuse which set fuse 0/5 and 0/6 and updt_fuse which burns bit 4 of 0/5. Before Image 2.6 we fused in mfgr_fuse 0x5062, which boots from the user partition of the eMMC. To workaround certain hangs we moved to fastboot mode and using the first bootpartition of the eMMC requiring a fuse value of 0x5072 which could be achived by the then added updt_fuse command. At the same time the mfgr_fuse command was changed to also fuse 0x5072, revert that second change so that one can fuse both values, one with just mfgr_fuse and the later with mfgr_fuse;updt_fuse. Note that the mfgr_fuse command is only needed at module production time, a customer might need to use updt_fuse when upgrading an older module to be compatible with a newer image.

The old geometry used to round down the ECC strength. This allows to compile a U-Boot which has the same ECC format used in current Linux kernels by adding this line to the board configuration header file: #define CONFIG_NAND_MXS_BCH_LEGACY_GEO Note that this leads to 14 bit ECC per 512 byte block, which requires 2149 bytes overall. The SoC's boot ROM is only able to handle pages up to 2112 bytes, hence this format cannot be used for the boot/flash configuration block (BCB/FCB). Note that upstream Linux can also calculate ECC using JEDEC/ONFI NAND chip parameters by using the fsl,use-minimum-ecc device tree property.
