2f8d8d6b3a arm: Move bootstage record for board_init_f() to after arch_cpu_init()
The timer may be inited in arch_cpu_init() so it is not safe to make a
bootstage mark before this is called. Arrange the code to fix this.

Note: The question was raised as to why we don't keep all archs in sync.
PowerPC doesn't have specific bootstage markers at present (although it
does use boot progress). I hope that the generic board series will solve
this problem in general, but in the meantime this is a real problem, and
only in ARM.

We now get a correct time for board_init_f:

Timer summary in microseconds:
       Mark    Elapsed  Stage
          0          0  reset
    100,000    100,000  spl_start

e2e3e2b1be arm: Add CONFIG_DISPLAY_BOARDINFO_LATE to display board info on LCD
This option displays board info after stdio is running, so that it will
appear on the LCD. If it is displayed earlier, the board info will appear
on the serial console but not on the LCD.

Here follows a blow-by-blow description.

1a. Without CONFIG_DISPLAY_BOARDINFO_LATE, on serial:

U-Boot 2011.12-02550-g037e1c5-dirty (Nov 15 2012 - 14:29:42) for SMDK5250

In:    mkbp-keyb
Out:   lcd
Err:   lcd

Hit any key to stop autoboot:  0
SMDK5250 #

1b. Without CONFIG_DISPLAY_BOARDINFO_LATE, on LCD (note machine info
is missing):

In:    mkbp-keyb
Out:   lcd
Err:   lcd
Net:   No ethernet found.
Hit any key to stop autoboot:  0
SMDK5250 #

2a. With CONFIG_DISPLAY_BOARDINFO_LATE, on serial:

U-Boot 2011.12-02550-g037e1c5 (Nov 15 2012 - 14:27:40) for SMDK5250

CPU:   S5PC520 @ 1700MHz
I2C:   ready
DRAM:  2 GiB Elpida DDR3 @ 800MHz
MMC:   S5P MSHC0: 0, S5P MSHC1: 1

*** Warning - bad CRC, using default environment

Model: Google Snow
In:    mkbp-keyb
Out:   lcd
Err:   lcd
Net:   No ethernet found.

SMDK5250 #

2b. With CONFIG_DISPLAY_BOARDINFO_LATE, on LCD (note machine info is present):

Model: Google Snow
In:    mkbp-keyb
Out:   lcd
Err:   lcd
Net:   No ethernet found.

Since the LCD is all that a typical user sees, it is useful to display
the model there.

We may be able to rearrange things some other way one day, but at
present this seems like a convenient way of getting the required
behaviour.

06fd853890 arm: Add CONFIG_DELAY_ENVIRONMENT to delay environment loading
This option delays loading of the environment until later, so that only the
default environment will be available to U-Boot.

This can address the security risk of untrusted data being used during boot.

Any time you load untrusted data you expose yourself to a bug in the
code. The attacker gets to choose the data so can sometimes carefully
craft it to exploit a bug. We try to avoid touching user-controlled
data during a verified boot unless strictly necessary. Since the
default environment is good enough in this case (or you would just
change it), this gets around the problem by just not loading the
environment.

When CONFIG_DELAY_ENVIRONMENT is defined, it is convenient to have a
run-time way of enabling loading of the environment. Add this to the
fdt as /config/delay-environment.

Note: This patch depends on http://patchwork.ozlabs.org/patch/194342/

eae78c3406 arm: Move fdt check earlier so that board_early_init_f() can use it
We want to use the fdt inside board_early_init_f(), so check for its
presence earlier in the pre-reloc init sequence.

So far ARM and microblaze are the only only ones that use
CONFIG_OF_CONTROL. Microblaze does not have the same init loop, and in
particular does not have the board_early_init_f() call. So a patch for
microblaze would have no meaning.

e05e5de7fa arm: move C runtime setup code in crt0.S
Move all the C runtime setup code from every start.S
in arch/arm into arch/arm/lib/crt0.S. This covers
the code sequence from setting up the initial stack
to calling into board_init_r().

Also, rewrite the C runtime setup and make functions
board_init_*() and relocate_code() behave according to
normal C semantics (no jumping across the C stack any
more, etc).

Some SPL targets had to be touched because they use
start.S explicitly or for some reason; the relevant
maintainers and custodians are cc:ed.

2ffb4beb50 pmic: Introduce power_init_board() method at ./lib/board.c file
It is necessary to introduce a new system wide function- power_init_board()

It turns out, that power initialization must be done as early as possible.
In the case of PMIC framework redesign, which aims to support multiple
instances of PMIC devices the initialization shall be performed just
after malloc configuration.

The power_init_board function is a weak function with default implementation.

09c2e90c11 unify version_string
This patch removes the architecture specific implementation of
version_string where possible. Some architectures use a special place
and therefore we provide U_BOOT_VERSION_STRING definition and a common
weak symbol version_string.

7eb29398c0 arm: add CONFIG_MACH_TYPE setting and documentation
CONFIG_MACH_TYPE is used to set the machine type number in the
common arm code instead of setting it in the board code.
Boards with dynamically discoverable machine types can still set the
machine type number in the board code.

566e5cf451 ARM: drop unsupported 'trab' board
The 'trab' board configuration is broken, and there is nobody who is
interested and willing to fix it.  Drop it.

This includes support for VFD displays which have always been used by
this board only.
