In include/blk.h, Simon suggested:
===>
/*
* These functions should take struct udevice instead of struct blk_desc,
* but this is convenient for migration to driver model. Add a 'd' prefix
* to the function operations, so that blk_read(), etc. can be reserved for
* functions with the correct arguments.
*/
unsigned long blk_dread(struct blk_desc *block_dev, lbaint_t start,
lbaint_t blkcnt, void *buffer);
unsigned long blk_dwrite(struct blk_desc *block_dev, lbaint_t start,
lbaint_t blkcnt, const void *buffer);
unsigned long blk_derase(struct blk_desc *block_dev, lbaint_t start,
lbaint_t blkcnt);
<===
So new interfaces are provided with this patch.
They are expected to be used everywhere in U-Boot at the end.
The exceptions are block device drivers, partition drivers and efi_disk
which should know details of blk_desc structure.

When we create an efi_disk device with an UEFI application using driver
binding protocol, the 'efi_driver' framework tries to create
a corresponding block device(UCLASS_BLK/IF_TYPE_EFI). This will lead to
calling a PROBE callback, efi_disk_probe().
In this case, however, we don't need to create another "efi_disk" device
as we already have this device instance.
So we should avoid recursively invoke further processing in the callback
function.

This function is expected to be called, in particular from dm's pre_remove
hook, when associated block devices no longer exist.
Add efi_disk_remove() function.
This function removes an efi_disk object for a raw disk device (UCLASS_BLK)
and related objects for its partitions (UCLASS_PARTITION).
So this function is expected to be called through driver model's "remove"
interface every time a raw disk device is to be disconnected.

This function creates an efi_disk object for a raw disk device (UCLASS_BLK)

In the next commit, CONFIG_EFI_SETUP_EARLY will become mandated
in order to support dynamic enumeration of efi_disk objects.
This can, however, be problematic particularly in case of file-based
variable storage (efi_variable.c, default).
Non-volatile variables are to be restored from EFI system partition
by efi_init_variables() in efi_init_obj_list(). When efi_init_obj_list()
is called in board_init_r(), we don't know yet what disk devices
we have since none of device probing commands (say, scsi rescan) has not
been executed at that stage.
So in this commit, a preparatory change is made; efi_init_obj_list() is
broken into the two functions;
* efi_init_early(), and
* new efi_init_obj_list()
Only efi_init_early() will be called in board_init_r(), which allows
us to execute any of device probing commands, either though "preboot"
variable or normal command line, before calling efi_init_obj_list() which
is to be invoked at the first execution of an efi-related command
(or at efi_launch_capsules()) as used to be.

A image_size parameter has been added to the bootefi parameter.

Up until commit 5f59518a7b ("efi_loader: setting boot device"), we
could boot an arbitrary blob with bootefi. Indeed, efi_run_image() even
has a special case for missing device paths indicating a payload that
was directly loaded via JTAG, for example.
Restore the ability to inject a UEFI payload into memory and `bootefi`
it. If the address passed isn't the last PE-COFF loaded, then we'll
wipe out the pre-existing DP/Image information and let efi_run_image()
synthesize a memory device path.
An image size is required if we're booting an arbitrary payload, and
the FDT argument has been changed to accept `-`. The size could be
deduced from the image header, but it's required anyways as an explicit
acknowledgment that one's trying to boot an arbitrary payload rather
than accidentally using the wrong address in the single-addr form.

Unless you have a spare Apple Silicon machine, getting access to
the serial port on Apple Silicon machines requires special
hardware. Given that most machines come with a built-in screen
the framebuffer is likely to be the most convenient output device
for most users. While U-Boot will output to both serial and
framebuffer, OSes might not. Therefore set stdout-path to point
at /chosen/framebuffer when a keyboard is connected to the machine.
This behaviour can be overridden by setting the "stdout" variable
in the U-Boot environment. I addition to that keep the serial
console as the default when running under the m1n1 hypervisor.
The m1n1 hypervisor virtualizes the serial port such that it
can be easily accessed from any other machine with a USB port.

Commit 690af71850 changed this condition
from an explicit
IS_ENABLED(CONFIG_SPL_SEPARATE_BSS)
to
CONFIG_IS_ENABLED(SEPARATE_BSS)
The documentation for CONFIG_IS_ENABLED() in include/linux/kconfig.h
implies that we will get the correct behaviour, but the actual behaviour
differs such that this condition is now always false.
This stopped TPL being able to load the device tree blob at least on the
ROCKPro64 board (RK3399 SoC), since the wrong device tree location was
chosen.
The issues causing this behaviour with CONFIG_IS_ENABLED() are:
1. The documentation implies that CONFIG_SPL_BUILD =>
CONFIG_SPL_<option> is considered before the TPL equivalent.
Actually, the TPL options have higher priority - see definition of
_CONFIG_PREFIX.
2. The documentation implies a fallthrough, eg. if CONFIG_SPL_BUILD is
defined but the CONFIG_SPL_<option> is not, then it will proceed to
check if CONFIG_TPL_BUILD
Actually, if CONFIG_TPL_BUILD is defined, then it stops there
and CONFIG_SPL_BUILD is not considered - see definition of
_CONFIG_PREFIX.
During TPL build, at least for the ROCKPro64, both CONFIG_TPL_BUILD
and CONFIG_SPL_BUILD are defined, but because of the above, only TPL
options are considered. Since there is no CONFIG_TPL_SEPARATE_BSS,
this fails.
