039cbaefcf OMAP3: igep00x0: add CONFIG_SYS_NS16550_BROKEN_TEMT
IGEP board PC16550D (ns16550) UART doesn't set the
Transmitter Empty (TEMT) Bit in SPL. This makes
U-Boot to hang while waiting for TEMT. Add the
CONFIG_SYS_NS16550_BROKEN_TEMT config option to
avoid this issue.

7de0fe1ac3 serial/ns16550: add an option to avoid hanging on broken platforms
Some platforms (e.g. IGEPv2 board) has a broken ns16550 UART that
does not set the TEMT bit when the transmitter is empty in SPL.
This makes U-Boot to hang while waiting for TEMT to be set.

Add a new option to avoid this:

CONFIG_SYS_NS16550_BROKEN_TEMT

16550 UART set the Transmitter Empty (TEMT) Bit when all output
has finished and the transmitter is totally empty. U-Boot waits
for this bit to be set to initialize the serial console. On some
broken platforms this bit is not set in SPL making U-Boot to
hang while waiting for TEMT. Define this option to avoid it.

0e29a24814 OMAP3: igep00x0: add CONFIG_SPL_BOARD_INIT for CONFIG_SPL_NAND_SUPPORT
When booting an IGEPv2 board from NAND with SPL, U-Boot hangs
trying to read the OMAP General Purpose Memory Controller (GPMC).

The reason is that the GPMC initialization function is called
inside spl_board_init() and this function is only executed when
CONFIG_SPL_BOARD_INIT is defined.

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

15a33e49de Add option to display customised memory information

might be useful to display the memory type (DDR2, DDR3) or manufacturer.

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.

44df5e8d30 arm: move flush_dcache_all() to just before disable cache
In Cortex-A15 architecture, when we run cache invalidate
the cache clean operation executes automatically.
So if there are any dirty cache lines before disabling the L2 cache
these will be synchronized with the main memory when
invalidate_dcache_all() runs in the last part of U-boot

The two functions after flush_dcache_all is using the stack. So this
data will be on the cache. After disable when invalidate is called the
data will be flushed from cache to memory. This corrupts the stack in
invalida_dcache_all. So this change is required to avoid the u-boot
hang.

So flush has to be done just before clearing CR_C bit

07b2c5c0e5 mtd/cfi: add support for SST 4KB sector granularity
Add support for SST 4KB sector granularity.

Many recent SST flashes, i.e. SST39VF3201B and similar of this family
are declared CFI-conformant from SST. They support CFI query, but implement
2 different sector sizes in the same memory: a 64KB sector (they call it
"block", std AMD erase cmd=0x30), and a 4KB sector (they call it "sector",
erase cmd=0x50). Also, CFI query on these chips, reading from address 0x2dh
of cfi query struct, detects a number of secotrs for the 4KB granularity
(flinfo shows it).

For all other aspects, they are CFI compliant, so, as Linux do, i think
it's a good idea to handle these chips in the CFI driver, with a fixup
to allow 4KB granularity, as should be expected, instead of 64KB.

136846d77f arm/km: remove duplicate code
This patch removes 2 small portions of board specific code that are
duplicated with common ARM code and thus unnecessary. These 2 portions
of code concern the mach id that is given by u-boot to the Linux kernel
to identify the system's MACH.

The first one was the possibility to change the MACH thanks to the
'mach_id' enviroment variable. This is possible thanks to the 'machid'
env variable (see arch/arm/lib/bootm.c:boot_jump_linux()).

The seconde one is the setting of the bi_arch_number. This is already
done in arch/arm/lib/board.c:board_init_f() since km_arm.h does #define
CONFIG_MACH_TYPE.

06610e1826 km/common: drop unneeded std* environment variables
These variables are only used if CONFIG_SYS_CONSOLE_IS_IN_ENV
is set. This isn't the case, so we can drop them safely.

2472216cac arm/km: fix memory settings
On kmcoge5un we faced some serious problems with the memory during
temperature tests. Reason was that we overwrite some registers for
memory settings which have to leave untouched. These where registers
0x20148 , 0x2014c and 0x20154.
So writing these registers is prohibited and this patch removes them
from all km related config files. Even if the problem was only
seen on kmcoge5un.

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.
