Since commit 56adbb387273 ("image.h: Tighten up content using handy
CONFIG_IS_ENABLED() macro."), I found my boards fail to boot Linux
because the commit changed the logic of macros it touched. Now,
IMAGE_ENABLE_RAMDISK_HIGH and IMAGE_BOOT_GET_CMDLINE are 0 for all
the boards.
As you can see in include/linux/kconfig.h, CONFIG_IS_ENABLE() (and
IS_ENABLED() as well) can only take a macro that is either defined
as 1 or undefined. This is met for boolean options defined in
Kconfig. On the other hand, CONFIG_SYS_BOOT_RAMDISK_HIGH and
CONFIG_SYS_BOOT_GET_CMDLINE are defined without any value in
arch/*/include/asm/config.h . This kind of clean-up is welcome,
but the options should be moved to Kconfig beforehand.
Moreover, CONFIG_IS_ENABLED(SPL_CRC32_SUPPORT) looks weird.
It should be either CONFIG_IS_ENABLED(CRC32_SUPPORT) or
IS_ENABLED(CONFIG_SPL_CRC32_SUPPORT). But, I see no define for
CONFIG_SPL_CRC32_SUPPORT anywhere. Likewise for the other three.
The logic of IMAGE_OF_BOARD_SETUP and IMAGE_OF_SYSTEM_SETUP were
also changed for SPL. This can be a problem for boards defining
CONFIG_SPL_OF_LIBFDT. I guess it should have been changed to
IS_ENABLED(CONFIG_OF_BOARD_SETUP).
In the first place, if we replace the references in C code,
the macros IMAGE_* will go away.

On AM43x devices, the address of SPL entry point depends on
the device type, i.e. whether it is secure or non-secure.
Further, for non-secure devices, the SPL entry point is different
between USB HOST boot mode, other "memory" boot modes (MMC, NAND)
and "peripheral" boot modes (UART, USB)
To add to the complexity, on secure devices, in addition to the
above differences, the SPL entry point can change because of the
space occupied by other components (other than u-boot or spl)
that go into a secure boot image.
To prevent the user from having to modify source files every time
any component of the secure image changes, the value of
CONFIG_SPL_TEXT_BASE has been set using a Kconfig option that

out.
With this patch we don't get spurious warnings when running EFI binaries
anymore.

sh: Fix build errors for generic board
This includes the following fixes:
- Define needed __init_end symbol - see initr_reloc_global_data()
- Drop SH-specific struct bd_info
- Add an empty relocate_code() function
This prevents build errors with generic board, but the code will still need
work. Perhaps this is a better alternative than deleting the code.

net: Optionally use pxe client arch from variable
The client architecture that we pass to a dhcp server depends on the target
payload that we want to execute. An EFI binary has a different client arch
than a legacy binary or a u-boot binary.
So let's parameterize the pxe client arch field to allow an override via
the distro script, so that our efi boot path can tell the dhcp server that
it's actually an efi firmware.

efi_loader: Select bounce buffers for known-bad boards
We know for certain that we have 32bit DMA hardware, but 64bit addresses
on LS2085A and ZynqMP, so let's enable EFI bounce buffers for all defconfigs
on these SoCs.

efi_loader: Add bounce buffer support
Some hardware that is supported by U-Boot can not handle DMA above 32bits.
For these systems, we need to come up with a way to expose the disk interface
in a safe way.
This patch implements EFI specific bounce buffers. For non-EFI cases, this
apparently was no issue so far, since we can just define our environment
variables conveniently.
arm: add initial support for Amlogic Meson and ODROID-C2
This adds platform code for the Amlogic Meson GXBaby (S905) SoC and a
board definition for ODROID-C2. This initial submission only supports
UART and Ethernet (through the existing Designware driver). DTS files
are the ones submitted to Linux arm-soc for 4.7 [1].

All members of the DMA descriptor must be 32-bit, even on 64-bit
architectures: change the type to u32 to ensure this. Also, fix

distro: Add efi pxe boot code
Now that we can expose network functionality to EFI applications,
the logical next step is to load them via pxe to execute them as
well.
This patch adds the necessary bits to the distro script to automatically
load and execute EFI payloads. It identifies the dhcp client as a uEFI
capable PXE client, hoping the server returns a tftp path to a workable
EFI binary that we can then execute.
To enable boards that don't come with a working device tree preloaded,
this patch also adds support to load a device tree from the /dtb directory
on the remote tftp server.
