908d0243ac core: drop const for struct driver_info
In order to prepare for a new support of phandle when OF_PLATDATA is used
drop the const for struct driver_info as this struct will need to be

addf358bac core: add support for U_BOOT_DRIVER_ALIAS
Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.

To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

e85497a930 sandbox: make RAM size configurable
Up to now the RAM size of the sandbox is hard coded as 128 MiB. This does
not allow testing the correct handling of addresses outside the 32bit
range. 128 MiB is also rather small when tracing functions where the trace
is written to RAM.

Provide configuration variable CONFIG_SANDBOX_RAM_SIZE_MB to set the RAM
size in MiB. It defaults to 128 MiB with a minimum of 64 MiB.

324ec5d7b4 spi: Remove unnecessary #ifdefs in header file
These prevent use of compile-time checks such as:

    if (CONFIG_IS_ENABLED(DM_SPI))

since, for example, if CONFIG_SPL_DM_SPI is not enabled then the
definitions are not included by spi.h and the C code will not build.

The #ifdefs are unnecessary since there are no conflicts with the pre-DM
code. In any case we have almost switched over to driver model for SPI.

Drop these #ifdefs from spi.h to fix a build warning on chromebook_coral
in the following patch.

7842749c35 linux/kconfig.h: create two- and three-argument versions of CONFIG_IS_ENABLED
This adds a bunch of preprocessor magic to extend the capabilities of
CONFIG_IS_ENABLED. The existing semantics of

  CONFIG_IS_ENABLED(FOO)

expanding to a 1 or 0 (depending on build context and the defined-ness
or not of the appropriate CONFIG_FOO/CONFIG_SPL_FOO/CONFIG_TPL_FOO)
are of course preserved. With this, one is also allowed a two-argument
form

  CONFIG_IS_ENABLED(FOO, (something))

which expands to something precisely when CONFIG_IS_ENABLED(FOO) would
expand to 1, and expands to nothing otherwise. It is, in other words,
completely equivalent to the three lines

  #if CONFIG_IS_ENABLED(FOO)
  something
  #endif

The second argument must be parenthesized in order to allow any
tokens, including a trailing comma, to appear - one use case for this
is precisely to make it a bit more ergonomic to build an array and
only include certain items depending on .config. That should increase
both readability and not least "git grep"ability.

A third variant is also introduced,

  CONFIG_IS_ENABLED(FOO, (xxx), (yyy))

which corresponds to

  #if CONFIG_IS_ENABLED(FOO)
  xxx
  #else
  yyy
  #endif

7d78a4547d linux/kconfig.h: remove unused helper macros
U-Boot does not have loadable modules, and nothing currently uses any
of the (CONFIG_)?IS_(BUILTIN|MODULE) macros - only
the (CONFIG_)?IS_ENABLED variants are ever used.

While I understand the desire to keep this somewhat synchronized with
linux, we've already departed by the introduction of the
CONFIG_IS_ENABLED extra logic, and deleting these makes the next patch
much simpler, since I won't have to duplicate a lot of logic for no
real gain (as there are no users).

b4f73886c4 linux/kconfig.h: simplify logic for choosing CONFIG_{SPL_, TPL_, }*
Instead of using the arg1_or_junk trick to pick between two choices,
with a bit of duplication between the branches (and most of the
CONFIG_TPL_BUILD case being redundant, as _IS_TPL is known to be
defined to 1 in that case), simply define a prefix that we inject
between CONFIG_ and the given config symbol.

This only requires one level of indirection (to get the
_CONFIG_PREFIX macro expanded before the token concatenation takes
place), and makes it easy to, say, introduce a CONFIG_HOSTTOOL_
prefix. [I would expect most HOSTTOOL_ symbols to just be def_bool y,
but it would allow us to clean up some of the ifdef HOSTCC mess in the
sources shared between U-Boot and host tools.]

9beac5daf7 video: Add support for copying to a hardware framebuffer
Some architectures use a cached framebuffer and flush the cache as needed
so that changes are visible. This is supported by U-Boot.

However x86 uses an uncached framebuffer with a 'write-combining' feature
to speed up writes.  Reads are permitted but they are extremely expensive.

Unfortunately, reading from the frame buffer is quite common, e.g. to
scroll it. This makes scrolling very slow.

Add a new feature which supports copying modified parts of the frame
buffer to the uncached hardware buffer. This speeds up scrolling by at
least 10x on x86 so the extra complexity cost seems worth it.

As a starting point, add the Kconfig, update the video structures to keep
track of the buffer and add a function to do the copy.

1f1a0f3db3 compiler_types.h: Re-introduce CONFIG_OPTIMIZE_INLINING for U-Boot
In the Linux kernel, support for forcing inline functions to be made
inline, rather than allowing the compiler to make its own choice has
been removed.  With respect to performance, modern GCC (and Clang) do a
good job at deciding when to, or not to, inline code and there are no
run-time requirements in Linux anymore.

There is one downside to this, which is final binary size.  On average
in U-Boot removing this support grows SPL by almost 1 kilobyte.  But
there are cases where it shrinks the binary by making better inline
choices than we had forced.

Start by re-introducing CONFIG_OPTIMIZE_INLINING as a global which
essentially reverts 889b3c1245de ("compiler: remove CONFIG_OPTIMIZE_INLINING entirely")
from Linux.

67f51b40ca compiler*.h: sync include/linux/compiler*.h with Linux 5.7-rc5
Copy these from Linux v5.7-rc5 tag.

This brings in some handy new attributes and is otherwise important to
keep in sync.

We drop the reference to smp_read_barrier_depends() as it is not
relevant on the architectures we support at this time, based on where
it's implemented in Linux today.  We drop the call to kasan_check_read()
as that is not relevant to U-Boot as well.

a7c81fc853 riscv: Add Sipeed Maix support
The Sipeed Maix series is a collection of boards built around the RISC-V
Kendryte K210 processor. This processor contains several peripherals to
accelerate neural network processing and other "ai" tasks. This includes a
"KPU" neural network processor, an audio processor supporting beamforming
reception, and a digital video port supporting capture and output at VGA
resolution. Other peripherals include 8M of sram (accessible with and
without caching); remappable pins, including 40 GPIOs; AES, FFT, and SHA256
accelerators; a DMA controller; and I2C, I2S, and SPI controllers. Maix
peripherals vary, but include spi flash; on-board usb-serial bridges; ports
for cameras, displays, and sd cards; and ESP32 chips. Currently, only the
Sipeed Maix Bit V2.0 (bitm) is supported, but the boards are fairly
similar.

Documentation for Maix boards is located at
<http://dl.sipeed.com/MAIX/HDK/>.  Documentation for the Kendryte K210 is
located at <https://kendryte.com/downloads/>. However, hardware details are
rather lacking, so most technical reference has been taken from the
standalone sdk located at
<https://github.com/kendryte/kendryte-standalone-sdk>.

bba8618c8e riscv: Add device tree for K210 and Sipeed Maix BitM
Where possible, I have tried to find compatible drivers based on the layout
of registers. However, many devices remain untested. All untested devices
have been left disabled, but some tentative properties (such as compatible
strings, and clocks, interrupts, and resets properties) have been added.

082faeb865 dm: Fix error handling for dev_read_addr_ptr
dev_read_addr_ptr had different semantics depending on whether OF_LIVE was
enabled. This patch converts both implementations to return NULL on error,
and converts all call sites which check for FDT_ADDR_T_NONE to check for
NULL instead. This patch also removes the call to map_physmem, since we
have dev_remap_addr* for those semantics.

f9c7d4f99f clk: Add K210 clock support
Due to the large number of clocks, I decided to use the CCF. The overall
structure is modeled after the imx code. Clocks parameters are stored in
several arrays, and are then instantiated at run-time. There are some
translation macros (FOOIFY()) which allow for more dense packing.

1a198cf886 clk: Add a bypass clock for K210
This is a small driver to do a software bypass of a clock if hardware
bypass is not working. I have tried to write this in a generic fashion, so
that it could be potentially broken out of the kendryte code at some future
date. For the K210, it is used to have aclk bypass pll0 and use in0 instead
so that the CPU keeps on working.

019ef9a3f3 clk: Add K210 pll support
This pll code is primarily based on the code from the kendryte standalone
sdk in lib/drivers/sysctl.c. k210_pll_calc_config is roughly analogous to
the algorithm used to set the pll frequency, but it has been completely
rewritten to be fixed-point based.
