11d59fe537 serial: serial_msm: fail probe if settings clocks fails
Failure to set the clocks will causes data abort exception when
trying to write to AHB uart registers.
This patch ensures that we don't touch these registers if clock
setting failed.

ffada23ca7 db820c: set clk node to be probed before relocation

d71975ae6e PCI: autoconfig: Don't allocate 64-bit addresses to 32-bit only resources
Currently, if we happen to allocate an address requiring 64 bits to a
device only supporting 32-bit BARs, the address eventually gets silently
truncated to 32 bits. Avoid this by adding a new flag to
pciauto_region_allocate() to bail out in such situations.

52ba907328 PCI: dm: Ignore 64-bit memory regions if CONFIG_SYS_PCI_64BIT not set
Currently, qemu_arm_defconfig and qemu_arm64_defconfig only work with
the 'highmem=off' parameter passed to QEMU's virt machine. The reason is
that when 'highmem' is not disabled, QEMU appends 64-bit a memory
resource to the PCI controller's regions property in DT in addition to
the 32-bit PCI memory window in low memory. And the current DT parsing
code picks the last (thus the 64-bit one) memory resource, whose address
eventually gets silently truncated to 32 bits because
CONFIG_SYS_PCI_64BIT is not set, which obviously causes PCI to break.

Avoid this problem by ignoring memory regions whose addresses are above
the 32-bit boundary when CONFIG_SYS_PCI_64BIT is not set.

d677bfe2f7 tpm: disociate TPMv1.x specific and generic code
There are no changes in this commit but a new organization of the code
as follow.

* cmd/ directory:
        > move existing code from cmd/tpm.c in cmd/tpm-common.c
	> move specific code in cmd/tpm-v1.c
	> create a specific header file with generic definitions for
	  commands only called cmd/tpm-user-utils.h

* lib/ directory:
        > move existing code from lib/tpm.c in lib/tpm-common.c
	> move specific code in lib/tpm-v1.c
	> create a specific header file with generic definitions for
	  the library itself called lib/tpm-utils.h

* include/ directory:
        > move existing code from include/tpm.h in include/tpm-common.h
	> move specific code in include/tpm-v1.h

Code designated as 'common' is compiled if TPM are used. Code designated
as 'specific' is compiled only if the right specification has been
selected.

All files include tpm-common.h.
Files in cmd/ include tpm-user-utils.h.
Files in lib/ include tpm-utils.h.
Depending on the specification, files may include either (not both)
tpm-v1.h or tpm-v2.h.

9f9ce3c369 tpm: prepare introduction of TPMv2.x support in Kconfig
Because both major revisions are not compatible at all, let's make them
mutually exclusive in Kconfig. This way we will be sure, when using a
command or a library function that it is supported by the right
revision.

Current drivers are currently prefixed by "tpm_", we will prefix TPMv2.x
files by "tpm2_" to make the distinction without moving everything.

The Kconfig menu about TPM drivers is now divided into two sections, one
for each specification. Compliant drivers with one specification will
only show up if this specification _only_ has been selected, otherwise a
comment is displayed.

Once a driver is selected by the user, it selects automatically a
boolean value, that is needed in order to activate the TPM commands.
Selecting the TPM commands will automatically select the right
command/library files.

This reverts commit 819f1e081c.

This check was introduced in order to cope with the size limitation we had
when we were still using the raw environment in MMC. However, this
introduces padding as well, which can result in an overly huge binary if
one wants to flash the environment to some other location.

Since we now have a FAT-based environment, this check is not so useful
anymore, so we can just drop it.

429fa25e17 ARC: init debug uart in early common arc code
The debug UART is intended for use very early in U-Boot to debug
problems before serial drivers are up.

Call debug_uart_init right before board_init_f.

385cbe298a rpi: Change load addresses to make more room for the kernel & DTB
As of Linux 4.16, a multiplatform AArch64 kernel with our distro config
takes 26M. The current space reservation leaves only 17M for the kernel
and if it goes over it, the initrd gets overwritten when loading the
kernel from the filesystem.

A similar problem happens on ARMv7 with the DTBs taken from the
downstream Raspberry Pi foundation kernel. I guess they compile them
with DT overlay support enabled which grows them just enough.

Fix both of these problems by rewriting the memory map, which now allows
kernels to be up to 36M and DTBs up to 1M. Also the comment block was
kind of obsolete ever since the introduction of AArch64 support and the
firmware-loaded DTB doesn't get placed at 0x100 anymore either, so that
is fixed as well.
