Today we typically enable CMD_SATA in order to have the SATA
functionality itself enabled, despite there being a clean split between
the two symbols. This in turn leads to potential configuration problems.
Split things so that SATA continues to be separate and not CMD_SATA
instead depends, functionally, on AHCI being enabled.
To do all of this:
- Have X86 select AHCI directly rather than "default y" it later.
- Make CMD_SATA be a default y option, given the split of platforms that
enabled SATA and did, or did not, enable CMD_SATA.
- Change "imply CMD_SATA" to "imply SATA"
- Correct TARGET_VEXPRESS64_JUNO because you cannot select SATA_SIL
without PCI (and in turn, SATA is needed for SATA_SIL).
- Update a number of defconfigs to have no functional change.

A few x86 platforms use a SYS_MALLOC_F_LEN value of 0x1000 or higher.
With the impending move to having DEVRES enabled by default, we will
need a little more room here. Raise the default value.

As the code is today, we get a warning about "select" statements on

This commit introduces a new configuration option X86_RUN_64BIT_NO_SPL
to allow building U-Boot as a 64-bit binary without using the SPL
(Secondary Program Loader). The motivation is to simplify the boot
process for certain x86-based platforms that do not require SPL, such as
those booting directly from a 64-bit coreboot firmware.
This update revises the `X86_RUN_64BIT` configuration to more accurately
describe its role as "32-bit SPL followed by 64-bit U-Boot." It
clarifies the sequence of operations during the boot process, where the
system transitions from a 32-bit SPL (Secondary Program Loader) to the
main 64-bit U-Boot.

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

Simon Glass <[email protected]> says:
This little series reprises the EFI-video fix, fixes a USB problem and
enables a boot script for coreboot.
It also moves to truetype fonts for coreboot and qemu-x86, since the
menus look much better and there are no strong size constraints.
With these changes it is possible to boot a Linux distro automatically
with U-Boot on x86, including when U-Boot is the second-stage
bootloader.
|
|
This is needed to support Truetype fonts. In any case, the compiler
expects SSE to be available in 64-bit mode. Provide an option to enable
SSE so that hardware floating-point arithmetic works.

Most of the functionality of zboot is contained in the logic which
handles a zimage. Create a separate Kconfig for the logic so that it can
(later) be used without the command itself being enabled.
Enable ZBOOT by default on x86, with the command depending on that. The
existing 'imply' can therefore be removed.

The U-Boot EFI app can run as a 64-bit program, so set the Kconfig
correctly in that case. Make sure it doesn't build SPL, since there is
no need to switch from 32 to 64 bit when running.

The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.
With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

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.

At present we assume that CAR (Cache-as-RAM) is used if HOBs (Hand-off
blocks) are not, since HOBs typically indicate that an FSP is in use, and
FSPs handle the CAR init.
However this is a bit indirect, and for FSP2 machines which use their own
CAR implementation (such as apollolake) but use the FSP for other
functions, the logic is wrong.
To fix this, add a dedicated Kconfig option to indicate when CAR is used.

This slimbootloader CPU type is to enable U-Boot as a payload which
runs on top of Slim Bootloader (https://github.com/slimbootloader).
The Slim Bootloader is designed with multi-stage architecture for
the execution from reset vector to OS booting, and supports QEMU,
Apollolake, Whiskeylake and Coffeelake platforms consuming Intel
FSP (https://github.com/IntelFsp) for silicon initialization
including CAR and memory initialization.
The Slim Bootloader generates new HOB (Hand Off Block) which are
serial port info, memory map info, performance data info and so on,
and passes it to a Payload. U-Boot as a payload will use these HOB
information for basic initialization such as serial console.
As an initial commit,
- Add CONFIG_SYS_SLIMBOOTLOADER to enable slimbootloader CPU type
- Add new arch/x86/cpu/slimbootloader directory with minimum codes
- Get hob_list pointer from Slim Bootloader
