f7848d90dd Allow CONFIG_REGEX to be disabled when CONFIG_NET
Instead of selecting REGEX when NET is enabled, make it the default, but
allow boards that are tiny to disable it and lose functionality on all
but the first Ethernet adapter.

cm-bf548, bf538f-ezkit, and bf533-stamp need this. None appear to have
more than one Ethernet interface.

09c3280754 mtd, nand: Move common functions from cmd_nand.c to common place
Move common functions from cmd_nand.c (for calculating offset
and size from cmdline paramter) to common place, so they could
used from other commands which use mtd partitions.

For onenand the arg_off_size() is left in common/cmd_onenand.c.
It should use now the common arg_off() function, but as I could
not test onenand I let it there ...

3850dbe833 blackfin: fix undefined reference to srand and rand
Commit 9ba9e85f3f (net: Fix NET_RANDOM_ETHADDR dependencies)
accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards.

Prior to that commit, those boards defined CONFIG_LIB_RAND, but not
CONFIG_NET_RANDOM_ETHADDR.  So, commit 9ba9e85f3f should not have
touched them, but in fact it ripped CONFIG_LIB_RAND off from all the
header files, which caused undefined reference to srand and rand.
CONFIG_LIB_RAND=y must be revived for such boards.

BTW, this commit indeed makes it better, but even with this fix,
three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not
build due to region 'ram' overflowed error.  This was cause by
commit 6eed3786c6 (net: Move the CMD_NET config to defconfigs)
because CMD_NET selects NET, and NET selects REGEX.  Eventually,
some boards were newly enabled with CONFIG_REGEX, increasing the
memory footprint.  A patch is expected to fix the build error.

9c7dea602e x86: Refactor PIRQ routing support
PIRQ routing is pretty much common in Intel chipset. It has several
PIRQ links (normally 8) and corresponding registers (either in PCI
configuration space or memory-mapped IBASE) to configure the legacy
8259 IRQ vector mapping. Refactor current Queensbay PIRQ routing
support using device tree and move it to a common place, so that we
can easily add PIRQ routing support on a new platform.

77d7fff8ce fdt: Fix handling of paths with options in them
After syncing the sunxi dts files with the upstream kernel dm/fdt sunxi
builds would no longer boot.

The problem is that stdout-path is now set like this in the upstream dts
files: stdout-path = "serial0:115200n8". The use of options in of-paths,
either after an alias name, or after a full path, e.g. stdout-path =
"/soc@01c00000/serial@01c28000:115200", is standard of usage, but something
which the u-boot dts code so far did not handle.

This commit fixes this, adding support for both path formats.

The U-Boot device trees are slightly different in a few places. Adjust them

concept of interrupts as distinct from GPIOs, so this difference remains.

aad78d2732 dm: x86: pci: Convert chromebook_link to use driver model for pci
Move chromebook_link over to driver model for PCI.

This involves:
- adding a uclass for platform controller hub
- removing most of the existing PCI driver
- adjusting how CPU init works to use driver model instead
- rename the lpc compatible string (it will be removed later)

This does not really take advantage of driver model fully, but it does work.
Furture work will improve the code structure to remove many of the explicit
calls to init the board.

f6eec89fa3 lzma: fix buffer bound check error further
Commit 4d3b8a0d fixed a problem with lzma decompress where it would
run out of bytes to decompress. The algorithm needs to know how many
uncompressed bytes it is expected to produce.

However, the fix introduced a potential buffer overrun, and causes
the compression test to fail (test_compression command in sandbox).

The correct fix seems to be to use the minimum of the expected number
of uncompressed bytes and the amount of output space available. That
way things work normally when there is enough space, and return an
error (without overrunning available space) when there is not.

e38d1cb28c initcall: add explicit hint if initcall was relocated
Commit "initcall: Improve debugging support" makes sense and indeed
simplifies process of matching initcalls executed with static
disassembly.

Until you are debugging relocation functionality.

Existign output may make you think that at some point execution somehow
returned back to non-relocated area. And there're many reasons/problems
that may provoke this behavior.

In order to make things clear let's add explicit mention in case initall
was actually relocated like this:
--->---
initcall: 810015f8
Relocation Offset is: 0efcf000
Relocating to 8ffcf000, new gd at 8fdced3c, sp at 8fdced20
initcall: 810015b8
initcall: 8ffd093c
initcall: 8ffd0a14
initcall: 81001940 (relocated to 8ffd0940)
initcall: 81001958 (relocated to 8ffd0958)
--->---

Note "unexpected" jump from 0x8f... area to 0x81... area.
Without explanation this raises many questions: execution jumped in
relocated area right as expected and then for some reason returned back?

But I hope comment in brackets will save some time for those curious
developers who are careful enough to catch "unexpected jump to pre-reloc
area" or those unlucky ones who'll have to deal with relocation
debugging.

59345b1f0f lib: errno: introduce errno_str(): returns errno related message
The functions error's numbers are standarized - but the error
messages are not.

The errors are often handled with unclear error messages,
so why not use an errno standarized messages.

Advantages:
- This could decrease the binary size.
- Appended with a detailed information,
  the error message will be clear.

This commit introduces new function:
- const char *errno_to_str(int errno)

The functions returns a pointer to the errno corresponding text message:
- if errno is null or positive number - a pointer to "Success" message
- if errno is negative - a pointer to errno related message

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.
