Re: [Linaro-uefi] [PATCH v4 03/12] Drivers/SdMmc: Adjust stack to fulfill Xenon controller demands

On Tue, Nov 29, 2016 at 03:40:20PM +0100, Marcin Wojtas wrote:

From: Jan Dąbroś jsd@semihalf.com

Because Xenon SD/MMC controller isn't fully compatible with SDHC, it demands some quirks on generic driver during initialization, i.e. limit bus width to 4, no voltage switch and hence disable highest speed modes, etc. Moreover, Xenon-specific init sequence is required, because it configures custom set of registers of Sd/Mmc PHY.

Two files containing Xenon-specific functions and defines were added.

Much cleaner, thanks.
