u-boot-dtb.bin is built by concatenating u-boot-nodtb.bin and u-boot.dtb.
u-boot-nodtb.bin, in turn, is generated by objcopy'ing the contents of
u-boot (U-Boot in ELF format) into a raw file.
In order to find the bundled FDT (u-boot.dtb), the code in lib/fdtdec.c
uses the _end symbol. Platform-specific linker scripts ensure that _end is
8-byte aligned, which is required by libfdt.
For the PowerPC MPC83xx platform, the ALIGN(8) directive was outside a
section, with the unfortunate effect that the potentially generated padding
bytes would not be copied by objcopy. This resulted in a discrepancy
between the _end symbol on the one hand, and the size of u-boot-nodtb.bin
and thus the starting location of the actual FDT on the other side. Under
these conditions, the FDT could not be found and boot would fail early.
This commit fixes it by moving the ALIGN(8) into the __u_boot_list section,
which is non-empty and thus copied into u-boot-nodtb.bin.

As exposed by "make randconfig", we have an issue with the dependencies
for REGMAP (and xPL variants). As this is a library function, it should
always be selected and not depended on by other functionality. This is
largely done correctly today, so just correct the few outliers.

This patch renames the board directory from board/freescale to
board/nxp because NXP now provides Board Support Packages (BSPs) and
tools for the former Freescale i.MX and other i.MX products.
All relevant references have been updated accordingly. This change does

With commit 0535e46d55d7 ("scripts/dtc: Update to upstream version
v1.7.2-35-g52f07dcca47c") it is now a fatal error to U-Boot if our
device tree is not 8-byte aligned. In commit 85f586035d75 ("ARM: OMAP2+:
Pad SPL binary to 8-byte alignment before DTB") Beleswar Padhi explains
that we must have ALIGN(x) statements inside of a section to ensure that
padding is included and not simply that the linker address counter is
incremented. To that end, this patch:
- Aligns the final section before _end by 8-bytes by adding '. =
ALIGN(8);' or changing an existing ALIGN(4) statement.
- Ensure that we do have alignment by adding an ASSERT so that when not
aligned we fail to link (and explain why).

Globals defined in headers can result in multiple-definition errors
while linking, if they are visible beyond the current translation unit.
This hasn't been a problem for initreg.h so far, but would become a
problem in the next patch, where I use a constant from initreg.h in a
second C file.

Instructions such as dcbi are in the X-form; they have RA and RB fields
and the effective address (EA) is computed as (RA|0)+(RB). In words,
this means that if RA is zero, the left-hand side of the addition is
zero, otherwise the corresponding GPR is used. r0 can never be used on
the left-hand side of a X-form instruction.
For D-form instructions such as addis, the Power ISA illustrates this in
the instruction pseudo-code:
if RA = 0 then RT <- EXTS(SI || 0x0000)
else RT <- (RA) + EXIS(SI || 0x0000)
In all of these cases, RA=0 indicates the value zero, not register r0.
I verified with gazerbeam_defconfig (MPC83xx) and qemu-ppce500_defconfig
(MPC85xx) that this patch results in the same machine code.

At startup, some RAM is needed (for instance for stack) before
DRAM is initialised.
One way to offer such RAM, used by mpc83xx, is to lock some entries
in the cache. To do that, MMU needs to be activated.
On mpc83xx having a QUICC Engine an alternative is to user some
part of from the Multi User RAM, like done on mpc8xx for instance.
For that, the MMU is not needed.
Activating the MMU is problematic because exception vectors are not
setup yet so in case of ISI or DSI that CPU will crash and reboot.
At the time being, MMU is activated regardless.
Only activate it when locking cache entries to provide initial RAM.

At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks. Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.
Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.

CONFIG_SYS_GBL_DATA_OFFSET
In the places where PowerPC references CONFIG_SYS_GBL_DATA_OFFSET it
does so as (CONFIG_SYS_INIT_RAM_ADDR + CONFIG_SYS_GBL_DATA_OFFSET). And
it defines CONFIG_SYS_GBL_DATA_OFFSET in the same manner that other
architectures define CONFIG_SYS_INIT_SP_OFFSET. Other architectures
define CONFIG_SYS_INIT_SP_ADDR as (CONFIG_SYS_INIT_RAM_ADDR +
CONFIG_SYS_INIT_SP_OFFSET) typically. Rename things within PowerPC for

The way board/keymile/Kconfig is written protects the options there from
being parsed on non-keymile platforms. We cannot however safely source
this file from multiple locations. This does not manifest as a problem
currently as there are no choice statements inside of this file (nor the
sub-Kconfig files it sources). However, moving some target selection to
one of these files exposes the underlying problem. Rework things so
that we have this file sourced in arch/Kconfig.

This converts removes the following symbols:

CONFIG_HAS_ETH1

This is because at this point, only the ids8313 platform was using the
code which was controlled by these symbols. In turn, this code already
performs error checking on being able to perform the device tree fixup.
Rather than convert these to Kconfig for a single platform, update the
code to not need these checks and remove them from all the platforms
they were unused on.
