Since commit 2580a2a7e7 ("mtd: nand: Increase max sizes of OOB and
Page size"), three boards (ph1_ld4, ph1_pro4, ph1_sld8) fail to build
with the following error message:
arm-linux-gnueabi-ld.bfd: SPL image plus BSS too big
They compile drivers/mtd/nand/denali_spl.c and it has a page_buffer
as static data:
static uint8_t page_buffer[NAND_MAX_PAGESIZE];
This buffer required 8KB in .bss section before that commit and now
it has been increased to 16KB. Given limited code/memory size for SPL,
it is not a good idea to allocate a page buffer statically. In the
first place, the load address 'dst' can be used as a page buffer.

The device might have already been probed during the call to
device_probe() on its parent device (e.g. PCI bridge devices).
In its parent device's probe routine, it might probe all of
its child devices via device_probe() thus the codes reenter
device_probe_child(). To support code reentrancy, test these
allocated memory against NULL to avoid memory leak, and return
to the caller if dev->flags has DM_FLAG_ACTIVATED set after
device_probe() returns, so that we don't mess up the device.

So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device
will try to initialize a keyboard device (for x86, it is i8042). But
if i8042 controller initialization fails (eg: there is no keyboard
connected to the PS/2 port), drv_video_init() just simply returns.
This kills the opportunity of using a usb keyboard later with the vga
console, as the vga initialization part is actually ok, only keyboard
part fails. Change the code logic to allow this.

The existing i8042 keyboard controller driver has some issues.
First of all, it does not issue a self-test command (0xaa) to the
controller at the very beginning. Without this, the controller
does not respond to any command at all. Secondly, it initializes
the configuration byte register to turn on the keyboard's interrupt,
as U-Boot does not normally allow interrupts to be processed.
Finally, at the end of the initialization routine, it wrongly
sets the controller to disable all interfaces including both
keyboard and mouse.

Per Intel FSP specification, we should call FSP notify API to

Unfortunately we have to put this call here as with driver model,
the enumeration is all done on a lazy basis as needed, so until
something is touched on PCI it won't happen.

This gem is really really rare, there was an actual float used in
the Altera DDR init code, which pulled in floating point ops from
the libgcc, just wow.
Since we don't support floating point operations the same way Linux
does not support them, replace this with an integer multiplication
and division combo. This removes some 2kiB of size from the SPL as
the floating point ops are no longer pulled in from libgcc.
This was detected by enabling CONFIG_USE_PRIVATE_LIBGCC=y , which
does not contain the floating point bits.
