Introduce board_init_f_mem() to handle early memory layout
At present on some architectures we set up the following before calling
board_init_f():
- global_data
- stack
- early malloc memory
Adding the code to support early malloc and global data setup to every
arch's assembler start-up is a pain. Also this code is not actually
architecture-specific. We can use common code for all architectures and
with a bit of care we can write this code in C.
Add a new function to deal with this. It should be called after memory
is available, with a pointer to the top of the area that should be used
before relocation. The function will set things up and return the lowest
memory address that it allocated/used. That can then be set as the top
of the stack.
Note that on some archs this function will use the stack, so the stack
pointer should be set to same value as is pased to board_init_f_mem().
A margin of 128 bytes will be left for this stack, so that it is not
overwritten. This means that 64 bytes is wasted by this early call.
This is not strictly necessary on several more modern archs, so we could
remove this at the cost of some arch-dependent code.
With this function there is no-longer any need for the assembler code to
zero global_data or set up the early malloc pointers.

lcd: split splash code into its own function
lcd_logo() currently performs tasks well beyond just displaying the logo.
It has code which displays splash image, it has logic which determines
when the different display features are displayed, and it is coupled with
the lcd console because it holds the responsibility of returning the
lcd console base address.
Make lcd_logo() just about the logo by:
* Moving splash image display code into a dedicated function
* Moving the logic regarding when various features are displayed to
lcd_clear() (which is arguably not the correct name for housing such
code either, but it is currently the most fitting location code wise)
* Move the responsibility of setting the console base address to
lcd_clear() too.

common/lcd code is full of platform-specific code and definitions, which

mx53loco: Fix boot hang during reboot stress test
Currently by running the following test:
=> setenv bootcmd reset
=> save
=> reset
, we observe a hang after approximately 20-30 minutes of stress reboot test.
Investigation of this issue revealed that when a single DDR chip select is used,
the hang does not happen. It only happens when the two chip selects are active.
MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence":
"The controller must keep the memory lines quiet (except for CK) for the ZQ
calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256
for other ZQCL and 64 for ZQCS)."
According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL:
"Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines.
Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)"
So make sure to activate one chip select at time (CS0 first and then CS1 later),
so that the required JEDEC delay is respected for each chip select.
With this change applied the board has gone through three days of reboot stress
test without any hang.

* we may use little-endian toolchain but build U-Boot for ether
endianess
* we may use non-multilibbed uClibc toolchain but build U-Boot for
whatever ARC CPU flavour that current GCC supports
