In order to calculate the capability, we use the below expression to check:
((dev_desc->lba * dev_desc->blksz)>0L)
If the capability is greater than 4GB (e.g. 8GB = 8 * 1024 * 104 * 1024),
the result will overflow, the low 32bit may be zero.

Therefore, change to check each variable to fix this potential issue.

This new make target "u-boot-img.bin" consists of the U-Boot
SPL image with the real, full-blown U-Boot image directly
attached to it. The full-blown U-Boot image has the mkimage
header included, with its load-address and entry-point.

This will be used by the upcoming a3m071 MPC5200 board port.

This patch enabled boards using the SPL framework to set
an entry point in the U-Boot mkimage image "u-boot.img".
Until now the entry point in the header has been set to 0.
By setting CONFIG_SYS_UBOOT_START in the board header, boards
can override this default location.

This will be used by the upcoming a3m071 MPC5200 board port.

With this patch, getenv_f() can be included easily into the SPL

will be used by an upcoming MPC5200 board port.

This patch enables the SPL framework to be used on powerpc platforms
and not only ARM.

timer_init() does not exist on PPC systems. The timer (decrementer) is
initialized and enabled in interrupt_init() here. And currently
interrupt_init() is called after relocation to SDRAM. Since the only
powerpc SPL implementation (a3m071) doesn't need a timer, let's remove
this timer_init() call for PPC systems.

This patch prevents u-boot from "spamming" random progress codes on
a port 80 "post card".
The previous version of this patch just removed the delays in the "slow"
IO functions, as they do not need to be slow, however, this patch is
less intrusive.

It uses another unused port that is often used by BIOSes (and the Linux
Kernel) for small delay timing purposes.

This patch builds upon the recently introduced CBMEM console
feature of coreboot.

CBMEM console uses a memry area allocated by coreboot to store
the console output. The memory area has a certain structure,
which allows to determine where the buffer is, the buffer size
and the location of the pointer in the buffer. This allows
different phases of the firmware (rom based coreboot, ram based
coreboot, u-boot after relocation with this change) to keep
adding text to the same buffer.

Note that this patch introduces a new console driver and adds the
driver to the list of drivers to be used for console output, i.e.
it engages only after u-boot relocates. Usiong CBMEM console for
capturing the pre-relocation console output will be done under a
separate change.

>From Linux, run the cbmem.py utility (which is a part of the coreboot
package) to see the output, e.g.:

vvvvvvvvvvvvvvvvv
SCSI:  AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode
flags: 64bit ilck stag led pmp pio
...
Magic signature found
Kernel command line: "cros_secure  quiet loglevel=1 console=tty2...
^^^^^^^^^^^^^^^^^

Note that the entire u-boot output fits into the buffer only if
the coreboot log level is reduced from the most verbose. Ether
the buffer size will have to be increased, or the coreboot
verbosity permanently reduced.

On kzm9g board (rmobile SoC), autoboot fails if serial console cable is not
connected.  When serial cable is not connected, serial error occurs and
some garbage comes in data register.
sh_serial_tstc() in serial_sh.c does not check error status and misunderstand
there is some input data.  It is the reason that autoboot fails.
This patch adds checking error status in sh_serial_tstc().
