d9fa344bac net: mediatek: fix sgmii selection for mt7622
Unlike other platforms, mt7622 has only one SGMII and it can be
attached to either gmac1 or gmac2. So the register field of the
sgmii selection differs from other platforms as newer platforms can
control each sgmii individually.

This patch adds a new capability for mt7622 to handle this case.

Andrew Goodbody <andrew.goodbody@linaro.org> says:

I had previously set CONFIG_64BIT for arm64.  This patchset does the

Select CONFIG_64BIT so that we pass the -m64 option (instead of -m32) to

Introduce CONFIG_SPL_64BIT and select it for architectures other than
x86 with 64 bit builds. Do not select it for x86 builds as x86 uses
a 32 bit SPL.
Ensure that when limits are set they use CONFIG_64BIT for U-Boot
proper and CONFIG_SPL_64BIT for SPL. This is to allow for the 32 bit
SPL build used by x86.

e094e2095e Gitlab: Make test.py stage only depend on binman et al testsuite
Our Gitlab pipeline is currently broken up in to several stages. This
was done with the thought process of "we should test tools and if
they're good test emulated targets and if they're good test real
hardware and if they're good test the world". However, in terms of that
first stage it only really matters that binman, et al are still
functional. And for a few years now Gitlab has had a "needs" keyword
that lets you refine pipeline dependencies. Use this to perform the
minor optimization of having test.py only require that tool testing job.
This will become more useful later when we add long running testsuites
that we do not want to block later jobs.

9897b640d6 gpio: mpc8xxx: Preserve pre-init state of outputs
The mpc8xxx_gpio driver contains a workaround for certain chips
where the previously written state of outputs cannot be read back
from the GPIO data (GPDAT) register (MPC8572/MPC8536). This workaround
consists of tracking the state of GPDAT in a "shadow register" (i.e. a
software variable). The shadow register is initialized to zero.

This results in a problem w.r.t. outputs that are configured to a
high (1) state before U-Boot runs, but not touched by U-Boot itself:
Due to the zero-initialization, these GPIOs end up being set to zero,
the first time that any other output is set.

To avoid such issues initialize the GPDAT shadow register to the value
previously held by any outputs, if possible. On MPC8572/MPC8536 this
should make no difference, i.e. the shadow register should be
initialized to zero on these chips.

This patch has been tested on a MPC8314E-based board.

3e132bd724 powerpc: Introduce and enforce assembler checks on GPR usage
PowerPC general-purpose registers are historically specified as plain
numbers (0-31), which makes them hard to distinguish from immediates.
For this reason, include/ppc_asm.tmpl defines aliases named r0-r31.
This can still lead to uncaught mistakes if a register is used in place
of a number.

Instead of (e.g.) 5 use %r5, which will result in an assembler warning
if used as a number. Turn these warnings into errors by passing
`--fatal-warnings` to the assembler.

I verified with gazerbeam_defconfig (MPC83xx) and qemu-ppce500_defconfig
(MPC85xx) that this patch results in the same machine code.

5cba7d4dab powerpc: Fix 0 vs. r0 confusion in X/D-form instructions
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.

13df47186e Merge patch series "Cleanup the LMB subsystem"
Ilias Apalodimas <ilias.apalodimas@linaro.org> says:

The LMB subsystem was used opportunistically for a number of years.
A while back Sughosh merged it with the EFI subsystem in order to have a
common allocator and avoid subsystems overwriting memory they shouldn't.

This is an initial cleanup of all the crud we gathered over the years.
There's no functional change expected from the patches as they just cleanup
some abstraction functions and rename a few variables to make more
sense.

I plan to make even bigger changes -- e.g I don't see the point of
having *_alloc() and *_reserve() versions of the functions since they
do the same thing and just cause confusion. lmb_alloc_addr_flags()
returning the base address on success makes little sense since we
already *request* the address on the function arguments, etc.
Since this patchset grew enough already, I'd like to get it in
before more refactoring happens.

It's worth noting that although some patches slightly increase the code
size due to an extra flags argument being carried around, the final
result is eventually smaller.

9c37f9ccbe lmb: Rename _lmb_alloc_addr() to lmb_alloc_addr_flags()
lmb_alloc_addr_flags() is a wrapper for _lmb_alloc_addr() and it's the
only function using it. Rename _lmb_alloc_addr() to lmb_alloc_addr_flags()
and remove the wrapper.

8692e10965 lmb: Rename free_mem to available_mem
free_mem is a misnomer. We never update it with the free memory for
LMB. Instead, it describes all available memory and is checked against
used_mem to decide whether an area is free or not.

So let's rename this field to better match its usage.

2a47acca5b lmb: Improve kernel-doc comments
Fix warnings from kernel-doc script. Improve and unify overall style of
kernel-doc comments in lmb source files. Move all kernel-doc comments
for public functions into the header, as recommended in U-Boot
documentation [1]:

    Non-trivial functions should have a comment which describes what
    they do. If it is an exported function, put the comment in the
    header file so the API is in one place. If it is a static function,
    put it in the C file.

This also takes care of existing duplication. While at it, do a bit of
cosmetic cleanups as well.

No functional change.

4b07407f94 lmb: Fix flags data type in lmb_add_region_flags()
rgnflags variable in lmb_add_region_flags() has incorrect type: it's
declared as phys_size_t when it should be enum lmb_flags. That
copy-paste mistake was firstly introduced in commit 59c0ea5df3 ("lmb:
Add support of flags for no-map properties"), and then copied further
into commit ed17a33fed ("lmb: make LMB memory map persistent and
global"). Fix it by using the correct type to match struct lmb_region
field.

No functional change.

5bc9d99a65 net: rswitch: Add PHY C22 access support
Implement C22 PHY access support in addition to C45 PHY access
support which is already present. This is used for PHYs which
do not support C45 access or which are C22 only.

The C22 access can be recognized when devad is set to -1 or
0xffffffff hex, which also matches MDIO_DEVAD_NONE macro. Test
for this special devad value and if it is set this way, perform
C22 access, otherwise perform C45 access.
