4dfe4b44cc x86: coreboot: Use vendor in the Kconfig
Use VENDOR_COREBOOT instead of TARGET_COREBOOT so we can have multiple
coreboot boards, sharing options. Only SYS_CONFIG_NAME needs to be
defined TARGET_COREBOOT.

92873f83d1 x86: Don't set up MTRRs if previously done
When starting U-Boot from a previous-stage bootloader we presumably don't
need to set up the variable MTRRs. In fact this could be harmful if the
existing settings are not what U-Boot uses.

Skip that step in this case.

cb80ff20f2 bootstage: Eliminate when not enabled
When we do not have bootstage enabled, rather than include an empty
dummy function, we just don't reference it.  This saves us space in some
tight builds.  This also shows a few cases where show_boot_progress was
incorrectly guarded before.

6fbe06a6ce x86: Discard .note.gnu.property sections
When switching to kernel.org x86_64 gcc 11.1.0 toolchain, u-boot.rom
built from qemu-x86_defconfig no longer boots anymore. Investigation
shows that U-Boot fails at a very early stage during the boot process,
in fdtdec_prepare_fdt() where fdt_check_header() complains that there
is not a valid device tree found at gd->fdt_blob which points to _end.
Now _end points to an allocated section .note.gnu.property which of
course is wrong.

This issue is however not seen when using the default Ubuntu 20.04 gnu
toolchain (gcc 9.3.0 with binutils 2.34). Further investigation shows
that it is caused by a behavior change of binutils v2.36 which is part
of the kernel.org gcc 11.1.0 toolchain, via the following commit:

  939b95c77bf2 ("Linux/x86: Configure gas with --enable-x86-used-note by default")

In fact, there was already a regression bug report [1] for binutils two
months ago, but the binutils folks did not think it is a bug :(

To resolve this, there are several options:

* pass -Wa,-mx86-used-note=no to gas
* pass -R .note.gnu.property to objcopy
* discard the section in the linker script

Linux kernel uses the discard way [2], so let's do the same for U-Boot.

236f2ec432 treewide: Convert macro and uses of __section(foo) to __section("foo")
This commit does the same thing as Linux commit 33def8498fdd.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;

uclass_get() call to ensure this, just like what was done before.

37c664e825 x86: Make sure the SPL image ends on a suitable boundary
The part of U-Boot that actually ends up in u-boot-nodtb.bin is not built
with any particular alignment. It ends at the start of the BSS section.
The BSS section selects its own alignment, which may larger.
This means that there can be a gap of a few bytes between the image
ending and BSS starting.

Since u-boot.bin is build by joining u-boot-nodtb.bin and u-boot.dtb (with
perhaps some padding for BSS), the expected result is not obtained. U-Boot
uses the end of BSS to find the devicetree, so this means that it cannot
be found.

Add 32-byte alignment of BSS so that the image size is correct and
appending the devicetree will place it at the end of BSS.

Example SPL output without this patch:

Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .text         000142a1  fef40000  fef40000  00001000  2**4
                  CONTENTS, ALLOC, LOAD, RELOC, READONLY, CODE
  1 .u_boot_list  000014a4  fef542a8  fef542a8  000152a8  2**3
                  CONTENTS, ALLOC, LOAD, RELOC, DATA
  2 .rodata       0000599c  fef55760  fef55760  00016760  2**5
                  CONTENTS, ALLOC, LOAD, RELOC, READONLY, DATA
  3 .data         00000970  fef5b100  fef5b100  0001c100  2**5
                  CONTENTS, ALLOC, LOAD, RELOC, DATA
  4 .binman_sym_table 00000020  fef5ba70  fef5ba70  0001ca70  2**2
                  CONTENTS, ALLOC, LOAD, DATA
  5 .bss          00000060  fef5baa0  fef5baa0  00000000  2**5
                  ALLOC

You can see that .bss is aligned to 2**5 (32 bytes). This is because of
the mallinfo struct in dlmalloc.c:

 17 .bss.current_mallinfo 00000028  00000000  00000000  000004c0  2**5
                  ALLOC

In this case the size of u-boot-spl-nodtb.bin is 0x1ba90. This matches up
with the _image_binary_end symbol:

fef5ba90 g       .binman_sym_table      00000000 _image_binary_end

But BSS starts 16 bytes later, at 0xfef5baa0, due to the 32-byte
alignment. So we must align _image_binary_end to a 32-byte boundary. This
forces the binary size to be 0x1baa0, i.e. ending at the start of bss, as
expected.

Note that gcc reports __BIGGEST_ALIGNMENT__ of 16 on this build, even
though it generates an object file with a member that requests 32-byte
alignment.

The current_mallinfo struct is 40 bytes in size. Increasing the struct to
68 bytes (i.e. just above a 64-byte boundary) does not cause the alignment
to go above 32 bytes. So it seems that 32 bytes is the maximum alignment
at present.

21096c0af3 x86: tangier: Find proper memory region for relocation
It appears that U-Boot works by luck on Intel Edison board because the amount
of RAM is less than 1 GB and standard way of calculating the top of it work
for this configuration. However, this won't work if the amount of RAM is
different and split differently in address space. We have to find the suitable
window correctly.

Find proper memory region for relocation by scanning MMAP SFI table in
board_get_usable_ram_top() callback.

According to the address map documentation the Main Memory is guaranteed to lie
in the 0..2 GB range, that's why we limit search by this range.

940185910f x86: call32: Append appropriate suffixes
Assembler is not happy:

arch/x86/cpu/call32.S: Assembler messages:
arch/x86/cpu/call32.S:36: Warning: no instruction mnemonic suffix given and no register operands; using default for `retf'

Fix this by adding appropriate suffixes to the assembler commands.

bcd4e6f3bd x86: Change how selection of ROMs works
Most x86 boards build a u-boot.rom which is programmed into SPI flash. But
this is not unique to x86. For example some rockchip boards can also boot
from SPI flash.

Also, at least on x86, binary blobs are sadly quite common. It is not
possible to build a functional image without them, and U-Boot needs to
know this at build time.

Introduce a new CONFIG_HAS_ROM option which selects whether u-boot.rom is
built and a new CONFIG_ROM_NEEDS_BLOBS option to indicate whether binary
blobs are also needed. If they are not needed, it is safe to build the ROM
always. Otherwise we still require the BUILD_ROM environment variable.

For now this affects only x86, but future patches will enable this for
rockchip too.

961420fa5f cpu: Convert the methods to use a const udevice *
These functions should not modify the device. Convert them to const so
that callers don't need to cast if they have a const udevice *.
