API_dev_write(va_list ap) is currently lacking the write support
to storage devices because, historically, those devices did not
implement block_write()
The solution has been tested by loading and booting a (patched)
GRUB instance in a QEMU vexpress-a9 environment. The disk write
operations were triggered with GRUB's save_env command.

dev_stor_get() is not able to find the next available device in the current
storage group when the previous enumerated device belongs to a different
group or class (e.g. network).
The root cause is the device group iterator not being reset after an
unsuccessful search for the last returned device so that the following
search for the next available device will start from beginning.
The issue has been identified by loading and booting GRUB in a QEMU
vexpress-a9 environment.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

At present CONFIG_CMD_SATA enables the 'sata' command which also brings
in SATA support. Some boards may wish to enable SATA without the command.
Add a separate CONFIG to permit this.

At present IDE support is controlled by CONFIG_CMD_IDE. Add a separate
CONFIG_IDE option so that IDE support can be enabled without requiring
the 'ide' command.
Update existing users and move the ide driver into drivers/block since
it should not be in common/.

Good evening,
I am trying to port FreeBSD to the ASUS Tinker Board, a computer based
on the Rockchip 3288 SoC. FreeBSD's boot loader (named loader(8)) needs
CONFIG_API to be enabled, but trying to build an U-Boot from trunk with
both CONFIG_API and CONFIG_BLK (as required for Rockchip SoC's?) leads
to the following build failure:
$ CROSS_COMPILE=arm-none-eabi- gmake tinker-rk3288_defconfig all

I applied the following fix, but the product doesn't boot. Perhaps

In a config with one MMC at device id '1' and no MMC at device id '0'
(a BeagleBone Black with no sd inserted for example), the current code
will first test to access the MMC 0 (sd port), seeing that no device is
present it will simply return that no more device are present for this
class.
This patch fixes this by testing all devices for each class.

This option currently enables both the command and the SCSI functionality.
Rename the existing option to CONFIG_SCSI since most of the code relates

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

When enabling CONFIG_API and chain-loading GRUB2 on jetson-tk1, only the
eMMC would show up as (hd0), but not the SD card, leading to GRUB not
finding its configuration and modules, falling back to a rescue shell.
This is because enum_ended would get set for !more after returning a
cookie for the first MMC device in group 3.
Fix this by properly setting the "more" argument also in the case of the
first storage device of a group.

This is an API for external (standalone) applications running on top of
U-Boot, and is meant to be more extensible and robust than the existing
jumptable mechanism. It is similar to UNIX syscall approach. See api/README
for more details.
Included is the demo application using this new framework (api_examples).
Please note this is still an experimental feature, and is turned off by
default.
