To: u-boot
Split userdata and boot partition support for eMMC update
and correct the description (update is supported).
The new configuration CONFIG_FASTBOOT_MMC_USER_SUPPORT
allows to activate support of userdata partition update,
based on target name=CONFIG_FASTBOOT_MMC_USER_NAME
This patch also removes the unnecessary dependency with
ARCH_MEDIATEK and EFI_PARTITION.

Update the code and the configs for eMMC boot and userdata
partitions acces
- FASTBOOT_MMC_BOOT_SUPPORT: boot partition 1 and 2 (erase/write)
- FASTBOOT_MMC_BOOT1_NAME: boot partition 1, default name="mmc0boot0"
- FASTBOOT_MMC_BOOT2_NAME: boot partition 2, default name="mmc0boot1"
This patch also removes the unnecessary dependency with
ARCH_MEDIATEK and EFI_PARTITION.

``mmc partconf <id> <arg> 0`` on the current <id> mmc device
to configure the eMMC boot partition with
<arg>: boot_ack boot_partition, so the command is:
$> fastboot oem partconf:<boot_ack> <boot_partition>
The partition_access argument is forced to 0 (userdata)

Hi Patrick,
I believe that the first two patches in this series can be replicated
with [1]. For example, if you currently use FASTBOOT_MMC_BOOT_SUPPORT
with FASTBOOT_MMC_BOOT1_NAME set to "mmc0boot1", leading to commands
like
$ fastboot erase mmc0boot1
You could instead do
$ fastboot erase 0.1:0
And the first behavior could be emulated by setting the environmental
variable "fastboot_partition_alias_mmc0boot1" to "0.1:0".
I would like to work towards deprecating Kconfigs for achieving this
particular use case. This is because everything is set at compile-time,
but we have existing tools which make this easy to do at run-time.
Favoring run-time configuration makes it easier to use one U-Boot for
different boards, and also makes it easier for users to modify U-Boot.
For the latter two patches, I think there are two existing solutions.
First, there is the patch to add "ucmd" support to fastboot. This allows
running arbitrary commands on the U-Boot side. However, this may be
unsuitable for systems which need to maintain a chain of trust (since
allowing arbitrary commands would allow arbitrary software to run).
With this in mind, FIT images allow for script sections. For example,
one could create an image tree source file like
/dts-v1/;
/ {
description = "Configuration script";
#address-cells = <1>;
images {
default = "script-1";
script-1 {
data = /incbin/("mmc.scr");
type = "script";
compression = "none";
signature {
algo = "sha1,rsa2048";
key-name-hint = "dev";
};
};
};
};
(or something similar; I haven't tested this). This would create a fit
with containing "mmc.scr". On the U-Boot side, running
fastboot 0
source
Would source any script contained within the FIT image (if it was
downloaded e.g. with "fastboot boot mmc.itb". I think this process would
work well for "run once" scripts like setting the mmc boot partitions.
Please let me know if any of the above suggestions would achieve the
functionality you need.
