rmobile/lowlevel_init_ca15.S are common in r8a7790, r8a7791 and r8a7794 of
rmobile SoCs. The initialize L2 cache in lowlevel_init_ca15.S only needed
for Cortex-A15. The r8a7794 is Cortex-A7, not Cortex-A15.
This adds Skip to initialize L2 cache when r8a7794.

rmobile/lowlevel_init_ca15.S are common in r8a7790 and r8a7791 of
rmobile SoC. But L2 cache of r8a7791 does not use L2CTLR[5].
This adds fix to set L2CTLR [5] only when the r8a7790.

In order for the gmac nic to work reliable on the Bananapi, we need to set
bits 10-12 GTXDC "GMAC Transmit Clock Delay Chain" of the GMAC clk register
(0x01c20164) to 3.
Without this about 9 out of 10 ethernet packets get lost, with this setting
there is no packet loss.
So far setting these bits is only necessary on the Bananapi, so this commit
solves this with a bit of #ifdef CONFIG_BANANAPI code. If in the future we
need to do something similar for other boards, we can create a specific
CONFIG_FOO option for this then.

Since exynos4 and exyno5 share many settings, we should move these into
a common file to avoid duplication.
In effect the changes are that all exynos boards now have EXT4 and FAT
write support. This affects exynos5250 and exynos5420 which previously
did not. This also disables the ext2 commands which are equivalent to
ext4 anyway.

With the driver model conversion we are going to be using driver model for
SPI and not for I2C. This works OK so long as a board doesn't need both
dm and non-dm versions of the cros_ec driver. Since pit uses SPI and snow
uses I2C we need to split the configs so that only one driver is compiled
for each platform.
We can fix this later when driver model supports I2C.

Unfortunately on Pit the AP has no direct access to the tps65090 but must
talk through the EC (over SPI) to the EC's I2C bus.
When driver model supports PMICs this will be relatively easy. In the
meantime the best approach is to duplicate the driver. It will be refactored
once driver model support is expanded.

Without NULL termination, various commands will read past the
end of input. In particular, this was noticed with error()
calls in cb_getvar and simple_strtoul() in cb_download.
Since the download callback happens elsewhere, the 4k buffer
should always be sufficient to handle command arguments.

This bit allows the MUSB controller to negotiate for high-speed mode when
the device is reset by the hub. If unset, Babble errors occur with
high-speed mass storage devices right after the first packet. This condition
is not caught by the interrupt handles in U-Boot, so no recovery is done,
and the USB communication is stuck.
To fix this, set the bit unconditionally, not only for
CONFIG_USB_GADGET_DUALSPEED but also for host-only modes.
