USDHC internal IC data handle bug already fixed on i.MX7ULP B0, so add HS200 support first. To let HS200 work on i.MX7ULP REV A3 board, need to do the following rework, otherwise, switch to HS200 will always meet error, caused by the voltage change make eMMC work not stable, this rework fix the eMMC I/O voltage to 1.8v, align with the MMC spec. 1,remove TF sd slot, replace eMMC chip 2,fix eMMC I/O voltage to 1.8v, remove R183, short TP3 and TP89 3,add R107, make eMMC boot work For i.MX7ULP REV B1 board, do not need this rework, board already fix the eMMC I/O voltage to 1.8v Acked-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Haibo Chen <haibo.chen@nxp.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
