11c4c92d91 ipq8064/storm: UART enable and various fixes
The original patch from chromium was  a bit of a mishmash.
Between that, rebasing and using the coreboot.org UART infrastructure,
the patch has changed a bit from the original. It seems reasonable to
keep these changes together.
- build in the ipq UART and turn on bootblock console
- sets LPAE and ROM header address
- adds cpd.c to storm

The original commit:
ipq8064: make UART driver work in bootblock

This patch it the last one in the chain adapting the ipq9064 UART
driver for use in coreboot. A new config option
(CONSOLE_SERIAL_IPQ806X) is being introduced to control inclusion of
the driver.

The previously introduced uart_wrapper.c is now included in the build
to provide the console driver structure used by ramstage.

Necessary configuration options are added to allow use of UART in the
bootblock.

0b341b341d ipq/arm: Redesign hooks for bootblock
The following patches had to be squashed
to properly build all the different ARM boards.

ipq8064: storm: re-arrange bootblock initialization

The recent addition of the storm bootblock initialization broke
compilation of Exynos platforms. The SOC specific code needs to be
kept in the respective source files, not in the common CPU code.

As of now coreboot does not provide a separate SOC initialization API.
In general it makes sense to invoke SOC initialization from the board
initialization code, as the board knows what SOC it is running on.

Presently all what's need initialization on 8064 is the timer. This
patch adds the SOC initialization framework for 8064 and moves there
the related code.

BUG=chrome-os-partner:27784

  . nyan_big, peach_pit, and storm targets build fine now.

arm: Redesign mainboard and SoC hooks for bootblock

This patch makes some slight changes to the way bootblock_cpu_init() and
bootblock_mainboard_init() are used on ARM. Experience has shown that
nearly every board needs either one or both of these hooks, so having
explicit Kconfigs for them has become unwieldy. Instead, this patch
implements them as a weak symbol that can be overridden by mainboard/SoC
code, as the more recent arm64_soc_init() is also doing.

Since the whole concept of a single "CPU" on ARM systems has kinda died
out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had
already been done on Storm/ipq806x, which is now adjusted to directly
use the generic hook.) Also add a proper license header to
bootblock_common.h that was somehow missing.

Leaving non-ARM32 architectures out for now, since they are still using
the really old and weird x86 model of directly including a file. These
architectures should also eventually be aligned with the cleaner ARM32
model as they mature.

476f7316a1 Copy u-boot sources as is and modify the tree to still build

drivers/serial/ipq806x_uart.c => src/console/ipq806x_console.c

Note that local timer.c gets overwritten with the original version. To
prevent a build breakage some shortly to be reverted modifications had
to be made to src/soc/qualcomm/ipq806x/Makefile.inc and
src/soc/qualcomm/ipq806x/cbfs.c.

b1709bd0b2 Provide ability to integrate with QComm SBLs
Ipq8064 SBLs initialize the hardware to prepare it to run an arbitrary
user provided bootloader. The only bootloader requirements imposed by
the SBLs are that it is concatenated with the SBL chunks in the
bootprm AND it uses MBN encapsulation (mostly to specify the size and
load address).

This patch adds configuration options to specify the location of the
SBL blobs and to require MBN encapsulation of the bootblock.
