If vboot successfully verifies a kernel, it will leave it in place and
basically ready to boot. The zeropage table which is part of the x86 boot
protocol is at the end of the kernel, though, instead of the beginning, and
because the image is already in place there's no need to copy it around.
This change refactors the code which implements the zboot command so that
the configuration of the zeropage table and loading the pieces of the
kernel into memory are done separately. Also, because the command line goes
before the zeropage table in vboot which is somewhat incompatible with the
normal protocol, where to put the command line is a now a parameter instead
of being hard coded.

This change also forces the lib_sysinfo structure to be in the .data

doesn't need to copy it over during relocation, and instead fills that
whole section with zeroes. If we really were booting from ROM that would be
appropriate, but we need some information from the coreboot tables (memory
size) before then and have to fill that structure before relocation. We
skirt u-boot's assumption by putting this in .data where it assumes there
is still read only but non-zero data.

U-boot itself generally builds with -nostdinc. This is because the
bootloader needs to be completely standalone. In the sandbox arch
though, we need a little bit of code to glue the u-boot world to the
host operating system, and we need to be able to access the host
libc's headers in order to do so.
Currently, we're using -I/usr/include to workaround the global
-nostdinc, but that doesn't work for everyone and for all headers.
Instead, let's filter out -nostdinc when building the os.c code.

(CONFIG_SPL_LIBCOMMON_SUPPORT / CONFIG_SPL_LIBGENERIC_SUPPORT) to let files in

Some SOCs have do not start up with their 'main' CPU. The first U-Boot
code may then be executed with a CPU which does not have a CP15, or not a
useful one.
Here we split the initialization of CP15 into a separate call, which can
be performed later if required.
Once the main CPU is running, you should call cpu_init_cp15() to perform
this init as early as possible.
Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not
need to change, this CP15 init is still skipped in that case. The only
impact for these boards is that the cpu_init_cp15() will be available
even if it is never used on these boards.

The Tegra2 boot path is more complicated than it needs to be. Since we want
to move to building most of U-Boot with ARMv7 and only a small part with
ARMv4T (for AVP) it should be as simple as possible.
This makes tegra2_start() into a simple function which either does AVP
init or A9 init depending on which core is running it. Both cores now
following the same init path, beginning at _start, and the special Tegra2
boot path code is no longer required.
Only two files need to be built for ARMv4T, and this is handled in the
Tegra2 CPU Makefile.

We want to move away from a special Tegra2 start-up, and just use
arch_cpu_init() instead. However, if we run board_init_f() from boot
we need to build it for ARMv4T, since the Tegra's AVP start-up CPU
does not support ARMv7.
The effect of this is to do the AVP init earlier, and in
arch_cpu_init(), rather that board_early_init_f().

Standard Debian powerpc and powerpcspe systems only include hard-float
libgcc in their native compilers, which causes scary build warnings when
building U-Boot.
Debian and other PowerPC-supporting distributions used to provide libgcc
and other libraries in a "nof" (soft-float) form in the "multilib"
packages. As they were completely unused by the distribution and
therefore tended to be very buggy it was decided to save some time on
the part of the maintainers and build-servers by removing them.
Admittedly, right now the linker warnings do not indicate any problems,
as the included routines do not use any floating point at all.
The concern is that if floating-point code were ever added it might
cause hard-float code to be unexpectedly included in U-Boot without
generating a hard error. This would cause unexplained crashes or
indeterminate results at runtime.
The easiest way to resolve this is to borrow the routines that U-Boot

We were not disabling external caches before jumping
to kernel. We were flushing all caches including
external caches and disabling caches globally in
CP15 System Control register. Apparently this is not
enough.
The bootstrap loader in Linux kernel that does decompression
enables data-caches again, flush them after use and disable
them before jumping to kernel proper. However, it's not aware
of the external caches.
Since we have left external cache enabled, external cache will
get used once caches are enabled globally, but it's not flushed
because decompressor is not aware of external caches. When it
jumps to kernel with caches disabled globally, we have stale
data in the external cache and a coherency problem.
This was breaking the boot for OMAP4 with latest mainline
kernel. The solution is to disable external caches in
cleanup_before_linux(). With this fix kernel is booting again.

The localbus controller node in the device tree is typically a root node,
even though the controller is part of CCSR. If we were to put the lbc
node under the SOC node, then the 'ranges' property in the lbc node would
translate through the 'ranges' property of the parent SOC node, and we
don't want that.
Since the lbc is a separate node, it's possible for the 'reg' property to
be wrong. This happened with the original version of p1022ds.dts, which
used a 32-bit value in the 'reg' address, instead of a 36-bit address.

Several macros are used to identify and locate the microcode binary image
that U-boot needs to upload to the QE or Fman. Both the QE and the Fman
use the QE Firmware binary format to package their respective microcode data,
which is why the same macros are used for both. A given SOC will only have
a QE or an Fman, so this is safe.
Unfortunately, the current macro definition and usage has inconsistencies.
For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman
firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address
of NAND. There's no way to know by looking at a variable how it's supposed
to be used.

When gcc compiles some 64 bit operations on a 32 bit machine, it generates
calls to small functions instead of instructions which do the job directly.
Those functions are defined in libgcc and transparently provide whatever
functionality was necessary. Unfortunately, u-boot can be built with a
non-standard ABI when libgcc isn't. More specifically, u-boot uses
-mregparm. When the u-boot and libgcc are linked together, very confusing
bugs can crop up, for instance seemingly normal integer division or modulus
getting the wrong answer or even raising a spurious divide by zero
exception.
This change borrows (steals) a technique and some code from coreboot which
solves this problem by creating wrappers which translate the calling
convention when calling the functions in libgcc. Unfortunately that means
that these instructions which had already been turned into functions have
even more overhead, but more importantly it makes them work properly.
To find all of the functions that needed wrapping, u-boot was compiled
without linking in libgcc. All the symbols the linker complained were
undefined were presumed to be the symbols that are needed from libgcc.
These were a subset of the symbols covered by the coreboot code, so it was
used unmodified.
To prevent symbols which are provided by libgcc but not currently wrapped
(or even known about) from being silently linked against by code generated
by libgcc, a new copy of libgcc is created where all the symbols are
prefixed with __normal_. Without being purposefully wrapped, these symbols
will cause linker errors instead of silently introducing very subtle,
confusing bugs.
Another approach would be to whitelist symbols from libgcc and strip out
all the others. The problem with this approach is that it requires the
white listed symbols to be specified three times, once for objcopy, once so
the linker inserts the wrapped, and once to generate the wrapper itself,
while this implementation needs it to be listed only twice. There isn't
much tangible difference in what each approach produces, so this one was
preferred.

This change adds an upper bound for symbols which are fixed up after u-boot

Signed-off-by: Gabe Black <gabeblack@chromium.org>
There are two blobs embedded into the u-boot image which are linked to run
at an address which is different from where they actually end up in the
ROM, one called "realmode" and one called "bios". There are realmode_setup
and bios_setup functions which prepare those blobs by copying them into the
location they're supposed to run from, among other things.
During u-boot relocation from ROM to RAM, the text and a few data segments
are copied over. The realmode and bios sections are not copied, and so the
only place they can be read from is their original location in the ROM.
Looking specifically at the bios blob, there are symbols defined in the
linker script called __bios_start and __bios_size which are defined to be
the start and size of the blob in the ROM.
In the bios_setup function, there seem to be two mistakes happening. First,
the offset from ROM to RAM is being added to __bios_start which implies that
this code expects to use the copy moved to RAM. No such copy is made, so
that's wrong. More subtly, when u-boot relocates itself, it goes through
all of the relocations stored in .rel.dyn and fixes them up. This has the
effect of transforming the __bios_start reference in bios_setup so that it
refers to the version in RAM (if one existed) instead of the one in ROM. To
correct for that, the offset actually needs to be subtracted out again to
translate the address back into the ROM.
The net effect is that for both blobs, a + needs to be changed to a -.

While video_font.h is useful even without referencing the font data, it
is not possible to be included multiple times because it defines font
data array right in the header.
This patch splits the font data array into video_font_data.h and so now
video_font.h can be included multiple times. This at least solves the
code duplication in board/mcc200/lcd.c.

Configuration header(CH) is 512 byte header attached to an OMAP
boot image that will help ROM code to initialize clocks, SDRAM
etc and copy U-Boot directly into SDRAM. CH can help us in
by-passing SPL and directly boot U-boot, hence it's an alternative
for SPL. However, we intend to support both CH and SPL for OMAP4/5.
Initialization done through CH is limited and is not equivalent
to that done by SPL. So U-Boot has to distinguish between the
two cases and handle them accordingly. This patch takes care
of doing this.

This patch adds the minimal support for OMAP5. The platform and machine
specific headers and sources updated for OMAP5430.
OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture.
It's a dual core SOC with GIC used for interrupt handling and SCU for cache
coherency.
Also moved some part of code from the basic platform support that can be made
common for OMAP4/5. Rest is kept out seperately. The same approach is followed
for clocks and emif support in the subsequent patches.
