If the pl011 is connected to another device which has hardware
flow-control on, characters are never received by the pl011.
Asserting RTS when flow-control is off will have no effect.
This is in line with how Linux behaves.

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

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.

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

In the approach this is done for env stored in NOR flash, as this
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.

It uses another unused port that is often used by BIOSes (and the Linux

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.

there is some input data. It is the reason that autoboot fails.

A hook is installed to configure PCI bus bridges as they encountered by u-boot.
The hook extracts the secondary bus number from the bridge's config space and
then recursively scans that bus.
On Coreboot, the PCI bus address space has identity mapping with the
physical address space, so declare it as such to ensure that the "pci_map_bar"
function used by some PCI drivers is behaving properly. This fixes the
EHCI PCI driver initialization on Stumpy.
This was tested as follows:
Ran the PCI command on Alex, saw devices on bus 0, the OXPCIe 952 on
bus 1, and empty busses 2 through 5. This matches the bridges
reported on bus 0 and the PCI configuration output from coreboot.

U-boot needs a host controller or "hose" to interact with the PCI busses
behind them. This change installs a host controller during initialization of
the coreboot "board" which implements some of X86's basic PCI semantics. This
relies on some existing generic code, but also duplicates a little bit of code
from the sc520 implementation. Ideally we'd eliminate that duplication at some
point.
It looks like in order to scan buses beyond bus 0, we'll need to tell u-boot's
generic PCI configuration code what to do if it encounters a bridge,
specifically to scan the bus on the other side of it.
