common: Move MD5 hash to hash_algo[] array.

MD5 is being called directly in some places, but it is not available
via hash_lookup_algo("md5"). This is inconsistent with other hasing
routines. To resolve this, add an "md5" entry to hash_algos[].

The #ifdef clause looks funnier than those for other entries. This is
because both MD5 and SPL_MD5 configs exist, whereas the other hashes
do not have "SPL_" entries. The long term plan is to get rid of the
ifdefs, so those should not be expected to survive much longer.

The md5 entry does not have .hash_init/update/finish members. That's
okay because hash_progressive_lookup_algo() will catch that, and
return -EPROTONOSUPPORT, while hash_lookup_algo() will return the

3 years agobtrfs: Use default subvolume as filesystem root
Matwey V. Kornilov [Sun, 1 Aug 2021 20:52:16 +0000 (23:52 +0300)]
btrfs: Use default subvolume as filesystem root

BTRFS volume consists of a number of subvolumes which can be mounted separately
from each other. The top-level subvolume always exists even if no subvolumes
were created manually. A subvolume can be denoted as the default subvolume i.e.
the subvolume which is mounted by default.

The default "default subvolume" is the top-level one, but this is far from the
common practices used in the wild. For instance, openSUSE provides an OS
snapshot/rollback feature based on BTRFS. To achieve this, the actual OS root
filesystem is located into a separate subvolume which is "default" but not
"top-level". That means that the /boot/dtb/ directory is also located inside
this default subvolume instead of top-level one.

However, the existing btrfs u-boot driver always uses the top-level subvolume
as the filesystem root. This behaviour 1) is inconsistent with

    mount /dev/sda1 /target

command, which mount the default subvolume 2) leads to the issues when
/boot/dtb cannot be found properly (see the reference).

This patch uses the default subvolume as the filesystem root to overcome
mentioned issues.

U-Boot support board detection at run time and based on it change DT.
This feature is implemented for SOM Kria platforms which contain two
eeproms which contain information about SOM module and CC (Carrier card).
Full U-Boot starts with minimal DT file defined by
CONFIG_DEFAULT_DEVICE_TREE which is available in multi DTB fit image.
It is using default setup of board_name variable initializaed to
DEVICE_TREE which corresponds to CONFIG_DEFAULT_DEVICE_TREE option.

When DTB_RESELECT is enabled board_detection() is called. Keep it your mind
that this code is called before relocation. board_detection() is calling
xilinx_read_eeprom() which fills board_info (xilinx_board_description)
structure which are parsed in board_name_decode().
Based on DT configuration and amount of nvmemX aliases name of the board is
composed by concatenating CONFIG_SYS_BOARD "-" <board_name> "-rev"
<board_revision> "-" <cc_name> "-rev" <cc_revision>.

If CC is not present or more are available it keeps going.

When board name is composed and returned from board_name_decode() it is
assigned to board_name variable which is used by
board_fit_config_name_match() which is called via fdtdec_setup() when it
goes over config options in multi dtb FIT image.

From practical point of view multi DTB image is key point here which has to
contain configs for detected combinations. Unfortunately as of now they
have to be full DTBs and DTBOs are not supported.

That's why configuration like:
config_X {
description = "zynqmp-board-cc";
fdt = "board", "cc";
};

needs to be squashed together with:
fdtoverlay -o zynqmp-board-cc -i arch/arm/dts/zynqmp-board.dtb \

especially
"Overall we have a deficiency in the UEFI implementation in that we
cannot deal with block devices added or removed after initialization."
there is a need to deal with removable media as usb/scsi/sata.

That's why bridge this gap in EFI implementation by resetting usb and
scsi resets to get all disks before efi_init_obj_list() is called.

In our standard boot flow, where we use distro boot, order is fixed as
"jtag mmc0 mmc1 qspi0 nand0 usb0 usb1 scsi0 pxe dhcp" with prioritizing
boot device added by commit 2882b39d564b ("arm64: zynqmp: Setup the first
boot_target at run time").
When device has ESP partition all devices should be detected because then
efi_disk_register() in efi_init_obj_list() is called only once.

The first such a device is sd/emmc(mmc0/mmc1) and then disks on usb/sata
are not handled at all.

The commit 6bb577dbb30f ("arm64: zynqmp: Disable

removable media wasn't solved that's why do it now via preboot command.

This current fix is workaround for now, this needs to be analysed
further. Zynqmp platform should behave the same as Versal, but we
did not encounter this issue as of now. So we are fixing it for
Versal only.

mmc: zynq_sdhci: Move setting tapdelay code to driver

Move tapdelay function calls to zynq_sdhci.c and make them static
inline. zynqmp_tap_delay.h has function prototypes for the functions
defined in tap_delays.c, which will not be needed anymore.

Remove tap_delays.c and zynqmp_tap_delay.h files.

mmc: zynq_sdhci: Add xilinx_pm_request() method to set tapdelays

Currently xilinx sdhci driver is using zynqmp_mmio_write() to set
tapdelay values and DLL resets. Continue to use this for SPL and mini
U-Boot where U-Boot will be executed at EL3 level.

Use firmware call xilinx_pm_request() using appropriate arguments to
set input/output tapdelays and also for DLL resets in regular flow(EL2).

Host driver should explicitly request DLL reset before ITAP (assert DLL)
and after OTAP (release DLL) to avoid issues in some cases. Also handle
error return where possible.
