Julius Werner 7a89d8550d rk3288: Adjust CBFS header and ROM offsets
Our CBFS header offset on rk3288 was very low and overlapped with the
end of the bootblock on recent Pinky builds. This can create all kinds
of fun effects like BSS variables suddenly being initialized to
something else than zero, in an effect that jumps somewhere else for
every slightest code size change.

This patch moves the CBFS header offset up a bit and the CBFS ROM offset
down (because there's really no point in leaving such a large gap). This
resolves our immediate booting problems, and I'll also start on a patch
to add further checks somewhere that catch these overlaps in the future.

BRANCH=None
BUG=None
TEST=Created a Pinky image from the exact same commit version as the
official 6443.0.0 build, with a KERNELREVISION string of the exact same
length as the builder (which for some arcane reason is different than
running emerge locally, shifting the whole bootblock around with it).
Confirmed that I saw the same "Not enough room for another
sub-pagetable!" hang, and that this patch fixes it.

coreboot README
-------------------------------------------------------------------------------

coreboot is a Free Software project aimed at replacing the proprietary BIOS
(firmware) found in most computers.  coreboot performs a little bit of
hardware initialization and then executes additional boot logic, called a
payload.

With the separation of hardware initialization and later boot logic,
coreboot can scale from specialized applications that run directly
firmware, run operating systems in flash, load custom
bootloaders, or implement firmware standards, like PC BIOS services or
UEFI. This allows for systems to only include the features necessary
in the target application, reducing the amount of code and flash space
required.

coreboot was formerly known as LinuxBIOS.


Payloads
--------

After the basic initialization of the hardware has been performed, any
desired "payload" can be started by coreboot.

See http://www.coreboot.org/Payloads for a list of supported payloads.


Supported Hardware
------------------

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

 * http://www.coreboot.org/Supported_Motherboards
 * http://www.coreboot.org/Supported_Chipsets_and_Devices


Build Requirements
------------------

 * gcc / g++
 * make

Optional:

 * doxygen (for generating/viewing documentation)
 * iasl (for targets with ACPI support)
 * gdb (for better debugging facilities on some targets)
 * ncurses (for 'make menuconfig')
 * flex and bison (for regenerating parsers)


Building coreboot
-----------------

Please consult http://www.coreboot.org/Build_HOWTO for details.


Testing coreboot Without Modifying Your Hardware
------------------------------------------------

If you want to test coreboot without any risks before you really decide
to use it on your hardware, you can use the QEMU system emulator to run
coreboot virtually in QEMU.

Please see http://www.coreboot.org/QEMU for details.


Website and Mailing List
------------------------

Further details on the project, a FAQ, many HOWTOs, news, development
guidelines and more can be found on the coreboot website:

  http://www.coreboot.org

You can contact us directly on the coreboot mailing list:
