fffff7268b dm: i2c: Make API accessible even without CONFIG_DM
Make the driver model I2C API available always, even if driver model
is not enabled. This allows for a 'soft' switch-over, where drivers can
use the new structures in code which is compiled but not yet used. This
makes migration easier in some cases.

Fix up the existing drivers which define their own 'struct i2c_msg'.

74d0186766 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.

2c8571703a malloc_simple: Return NULL on malloc failure rather then calling panic()
All callers of malloc should already do error checking, and may even be able
to continue without the alloc succeeding.

Moreover, common/malloc_simple.c is the only user of .rodata.str1.1 in
common/built-in.o when building the SPL, triggering this gcc bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54303

Causing .rodata to grow with e.g. 0xc21 bytes, nullifying all benefits of
using malloc_simple in the first place.

4fe49d7bec lsxl: switch from bootm to bootz for boot commands
Use the bootz command to load zImages in case of any new boot scripts. Only
the legacy one will still use bootm. Apart form the fact, that this will
simplify the image generation process, it saves one copy of the kernel
image: Common practice is to generate an uImage with a loading address of
0x8000. This uImage contains a compressed zImage, which will unpack the
kernel image to the beginning of the RAM. But because there is already the
compressed image the uncompressor first relocates the compressed image to a
higher location. The load address is encoded into the uImage which is
generated by the distributions and thus cannot be easily changed. By using
the bootz command we can load the compressed image to a higher memory
address and the decompressor doesn't have to reloacte the image.

145df6fe2a lsxl: place the dtb below the inital ramdisk
The dtb was loaded at a memory address after the initial ramdisk. Thus a
large ramdisk would overwrite the dtb. Move it to "ramdisk_start - 64k".
64k should be enough for the device tree blob. Also the kernel
documentation arm/Booting suggests to put the dtb before the initial
ramdisk.

bc2ad9f04d lsxl: use default load addresses for legacy boot
The load addresses for the bootcmd_legacy script were taken from the
original bootloader from Buffalo. But newer kernels are too big and the
uncompressing will overwrite parts of the initial ramdisk. Therefore,
we switch to the load addresses which are also used by the other boot
script.

This patch is to implement pmic_mode_init function, and add prototype
in header file.

This function is to set switching mode for pmic buck regulators to

Mode:
OFF: The regulator is switched off and the output voltage is discharged.
PFM: In this mode, the regulator is always in PFM mode, which
     is useful at light loads for optimized efficiency.
PWM: In this mode, the regulator is always in PWM mode operation
     regardless of load conditions.
APS: In this mode, the regulator moves automatically between
     pulse skipping mode and PWM mode depending on load conditions.

7bf71d1f55 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.
