2015-09-02mxc: ocotp fix hole in shadow registersPeng Fan
There is a hole in shadow registers address map of size 0x100 between bank 5 and bank 6 on iMX6QP, iMX6DQ, iMX6SDL, iMX6SX and iMX6UL. Bank 5 ends at 0x6F0 and Bank 6 starts at 0x800. When reading the fuses, we should account for this hole in address space. Similar hole exists between bank 14 and bank 15 of size 0x80 on iMX6QP, iMX6DQ, iMX6SDL and iMX6SX. Note: iMX6SL has only 0-7 banks and there is no hole. Note: iMX6UL doesn't have this one. When reading, we use register offset, so need to account for holes to get the correct address. When writing, we use bank/word index, there is no need to account for holes, always use bank/word index from fuse map.

2015-09-02mxs_ocotp: Shift the HBUS divider correctlyChris Smith
When the original HBUS divider value is retrieved in mxs_ocotp_scale_hclk() for the purpose or restoring it back later, the value is not shifted by the HBUS divider offset in that register. This is not a problem, since the shift is zero on all MXS hardware. Add the shift anyway, for completeness and in case FSL ever decides to re-use this driver on future designs.

2015-08-31pinctrl: add pin control uclass supportMasahiro Yamada
This creates a new framework for handling of pin control devices, i.e. devices that control different aspects of package pins. This uclass handles pinmuxing and pin configuration; pinmuxing controls switching among silicon blocks that share certain physical pins, pin configuration handles electronic properties such as pin- biasing, load capacitance etc. This framework can support the same device tree bindings, but if you do not need full interface support, you can disable some features to reduce memory foot print. Typically around 1.5KB is necessary to include full-featured uclass support on ARM board (CONFIG_PINCTRL + CONFIG_PINCTRL_FULL + CONFIG_PINCTRL_GENERIC + CONFIG_PINCTRL_PINMUX), for example. We are often limited on code size for SPL. Besides, we still have many boards that do not support device tree configuration. The full pinctrl, which requires OF_CONTROL, does not make sense for those boards. So, this framework also has a Do-It-Yourself (let's say simple pinctrl) interface. With CONFIG_PINCTRL_FULL disabled, the uclass itself provides no systematic mechanism for identifying the peripheral device, applying pinctrl settings, etc. They must be done in each low-level driver. In return, you can save much memory footprint and it might be useful especially for SPL. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-08-31sunxi_nand_spl: Remove NAND_SUNXI_SPL_SYNDROME_PARTITIONS_ENDHans de Goede
We only ever use syndrome mode for the partitions which contain the SPL, as that is required for the BROM to be able to read the SPL. Instead of using some arbritray limit for deciding whether or not to use syndrome, be smart and check if u-boot-dtb.bin is directly behind the SPL, if it is not then it is on its own partition and we should not use syndrome. Note the reason why we only use syndrome mode for the SPL is because it comeswith weaker randomization, introducing a risk for more bit errors, so we want to avoid it when possible.

We eventually want to add full nand support, since it makes no sense to build SPL with nand support and u-boot without, or the other way around, a single option will suffice.

2015-08-31sunxi_nand_spl: Add support for backup boot partitionsHans de Goede
The BROM does not care / use bad page markings, instead it deals with any bad pages in the first erase-block by simply trying to load "boot0" from the next erase-block.

2015-08-31sunxi_nand_spl: Auto detect nand configuration parametersHans de Goede

This allows us to get rid of various Kconfig settings, and is necessary to support generic boards like the mk802 which have seen many production runs with different nands. The full blown u-boot/kernel nand driver uses the nand id to determine this info, for the SPL we do as the BROM does and simply try a few standard configs. Note the table only contains configs which are known to actually be used, rather then all the configs the BROM tries.

This saves CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE (typically 1k) in SPL size, which is a lot on the total 24k we have.
