2017-05-08Add ARM errata workaround 852421 and 852423 for Cortex-A17Nisal Menuka
ARM errata 852421 and 852423 applies to r1p0, r1p1 and r1p2 revisions of Cortex-A17 processors. These workarounds exist in Linux kernel and I thought it would be better to add them in to U-Boot. Signed-off-by: Nisal Menuka <nisalmenuka23@gmail.com>

2017-05-08aspeed: Refactor SCU to use consistent mask & shiftmaxims@google.com

2017-05-08aspeed: Add support for Clocks needed by MACsmaxims@google.com
Add support for clocks needed by MACs to ast2500 clock driver. The clocks are D2-PLL, which is used by both MACs and PCLK_MAC1 and PCLK_MAC2 for MAC1 and MAC2 respectively. The rate of D2-PLL is hardcoded to 250MHz -- the value used in Aspeed SDK. It is not entirely clear from the datasheet how this clock is used by MACs, so not clear if the rate would ever need to be different. So, for now, hardcoding it is probably safer. The rate of PCLK_MAC{1,2} is chosen based on MAC speed selected through hardware strapping. So, the network driver would only need to enable these clocks, no need to configure the rate.

2017-05-08aspeed: AST2500 Pinctrl Drivermaxims@google.com
This driver uses Generic Pinctrl framework and is compatible with the Linux driver for ast2500: it uses the same device tree configuration. Not all pins are supported by the driver at the moment, so it actually compatible with ast2400. In general, however, there are differences that in the future would be easier to maintain separately.

2017-05-08aspeed: Refactor AST2500 RAM Driver and Sysreset Drivermaxims@google.com
This change switches all existing users of ast2500 Watchdog to Driver Model based Watchdog driver. To perform system reset Sysreset Driver uses first Watchdog device found via uclass_first_device call. Since the system is going to be reset anyway it does not make much difference which watchdog is used. Instead of using Watchdog to reset itself, SDRAM driver now uses Reset driver to do that. These were the only users of the old Watchdog API, so that API is removed. This all is done in one change to avoid having to maintain dual API for watchdog in between.

With 3f66149d9fb4 we no longer have a common call fdt_fixup_ethernet. This was fine to do on PowerPC as they largely had calls already in ft_cpu_fixup. On ARM however we largely relied on this call. Rather than introduce a large number of changes to ft_cpu_fixup / ft_board_fixup we recognize that this is a common enough call that we should be doing it in a central location. Do it early enough that we can do any further updates in ft_cpu_fixup / ft_board_fixup.
