effcf067df x86: Add initial video device init for Intel GMA
Intel's Graphics Media Accelerator (GMA) is a generic name for a wide range
of video devices. Add code to set up the hardware on ivybridge. Part of the
init happens in native code, part of it happens in a 16-bit option ROM for
those nostalgic for the 1970s.

1eebd14b79 vsprintf: Add modifier for phys_addr_t
Provide a new modifier to vsprintf() to print phys_addr_t variables to
avoid having to cast or #ifdef when printing them out. The %pa modifier
is used for this purpose, so phys_addr_t variables need to be passed by
reference, like so:

	phys_addr_t start = 0;

	printf("start: %pa\n", &start);

Depending on the size of phys_addr_t this will print out the address
with 8 or 16 hexadecimal digits following a 0x prefix.

65dd74a674 x86: ivybridge: Implement SDRAM init
Implement SDRAM init using the Memory Reference Code (mrc.bin) provided in
the board directory and the SDRAM SPD information in the device tree. This
also needs the Intel Management Engine (me.bin) to work. Binary blobs
everywhere: so far we have MRC, ME and microcode.

SDRAM init works by setting up various parameters and calling the MRC. This
in turn does some sort of magic to work out how much memory there is and
the timing parameters to use. It also sets up the DRAM controllers. When
the MRC returns, we use the information it provides to map out the
available memory in U-Boot.

U-Boot normally moves itself to the top of RAM. On x86 the RAM is not
generally contiguous, and anyway some RAM may be above 4GB which doesn't
work in 32-bit mode. So we relocate to the top of the largest block of
RAM we can find below 4GB. Memory above 4GB is accessible with special
functions (see physmem).

It would be possible to build U-Boot in 64-bit mode but this wouldn't
necessarily provide any more memory, since the largest block is often below
4GB. Anyway U-Boot doesn't need huge amounts of memory - even a very large
ramdisk seldom exceeds 100-200MB. U-Boot has support for booting 64-bit
kernels directly so this does not pose a limitation in that area. Also there
are probably parts of U-Boot that will not work correctly in 64-bit mode.
The MRC is one.

There is some work remaining in this area. Since memory init is very slow
(over 500ms) it is possible to save the parameters in SPI flash to speed it
up next time. Suspend/resume support is not fully implemented, or at least
it is not efficient.

With this patch, link boots to a prompt.

cba1da495d include: move various macros to include/linux/kernel.h
U-Boot has imported various utility macros from Linux
scattering them to various places without consistency.

In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN,
container_of, DIV_ROUND_UP, etc.
In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.

Moreover, we are suffering from too cluttered include/common.h.

This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.

Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.

does not. (y is incremented twice.)

ad3fda521b lib: lmb: fix overflow in __lmb_alloc_base w/ large RAM
If a 32-bit system has 2GB of RAM, and the base address of that RAM is
2GB, then start+size will overflow a 32-bit value (to a value of 0).

__lmb_alloc_base is affected by this; it calculates the minimum of
(start+size of RAM) and max_addr. However, when start+size is 0, it
is always less than max_addr, which causes the value of max_addr not
to be taken into account when restricting the allocation's location.

Fix this by calculating start+size separately, and if that calculation
underflows, using -1 (interpreted as the max unsigned value) as the
value instead, and then taking the min of that and max_addr. Now that
start+size doesn't overflow, it's typically large, and max_addr
dominates the min() call, and is taken into account.

The user-visible symptom of this bug is that CONFIG_BOOTMAP_SZ is ignored
on Tegra124 systems with 2GB of RAM, which in turn causes the DT to be
relocated at the very end of RAM, which the ARM Linux kernel doesn't map
during early boot, and which causes boot failures. With this fix,
CONFIG_BOOTMAP_SZ correctly restricts the relocated DT to a much lower
address, and everything works.
