xilinx: Disable ARCH_FIXUP_FDT_MEMORY
Based on DT spec you can have one memory node which multiple ranges or
multiple nodes.
fdt_fixup_memory_banks() is not implemented in a correct way when multiple
memory nodes are present because all ranges are put it to the first memory
node found. And next memory nodes are kept in DT which ends up in the same
range specification in the same DT.
Here is what it is happening.
Origin DT.
memory@0 {
device_type = "memory";
reg = <0x0 0x0 0x0 0x80000000>;
};
memory@
800000000 {
device_type = "memory";
reg = <0x8 0x00000000 0x0 0x80000000>;
};
After fdt_fixup_memory_banks()
memory@0 {
device_type = "memory";
reg = <0x0 0x0 0x0 0x80000000>, <0x8 0x00000000 0x0 0x80000000>;
};
memory@
800000000 {
device_type = "memory";
reg = <0x8 0x00000000 0x0 0x80000000>;
};
As is visible memory@0 node got second range but there is still
memory@
800000000 node present and 2G range is listed twice.
The solution can't be that second node is removed because it can be
referenced already that's why it is better for us to disable this option
for now.

xilinx: zynqmp: Initialize usb and scsi via preboot
Based on thread
https://lists.denx.de/pipermail/u-boot/2021-June/451828.html
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
EFI_CAPSULE_ON_DISK_EARLY") also pointed out on this issue but detection of
removable media wasn't solved that's why do it now via preboot command.
I have tested cases without usb and scsi and there is no problem with
calling resets without devices itself.

As per SD spec when SD host controller is reset, it takes 1000msec

the sd bus voltage.
In case of warm/subsystem reboot, due to unstable card detect state
host controller is disabling the sd bus voltage to sd card causing
sd card timeout error. So we wait for a maximum of 1000msec to get
the card detect state stable before we enable the sd bus voltage.

fs/squashfs: Fix some hardlinks reading the wrong inode
In SquashFS, the contents of a directory is stored by
squashfs_directory_entry structures which contain the file's name, inode
and position within the filesystem.
The inode number is not stored directly; instead each directory has one
or more headers which set a base inode number, and files store the
offset from that to the file's inode number.
In mksquashfs, each inode is allocated a number in the same order as
they are written to the directory table; thus the offset from the
header's base inode number to the file's inode number is usually
positive.
Hardlinks are simply stored with two directory entries referencing the
same file. This means the second entry will thus have an inode number
much lower than the surrounding files. Since the header's base inode
number comes from the first entry that uses the header, this delta will
usually be negative.
Previously, U-Boot's squashfs_directory_entry.inode_offset field was
declared as an unsigned value. Thus when a negative value was found, it
would either resolve to an invalid inode number or to that of an
unrelated file.
A squashfs image to test this can be created like so:
echo hi > sqfs_test_files/001-root-file
mkdir sqfs_test_files/002-subdir
touch sqfs_test_files/002-subdir/003-file
ln sqfs_test_files/{001-root-file,002-subdir/004-link}
mksquashfs sqfs_test_files/ test.sqfs -noappend
Note that squashfs sorts the files ASCIIbetacally, so we can use the
names to control the order they appear in. The ordering is important -
the first reference to the file must have a lower inode number than the
directory in which the second reference resides, and the second
reference cannot be the first file in the directory.
Listing this sample image in U-Boot results in:
=> sqfsls virtio 2 002-subdir
0 003-file
Inode not found.
0 004-link

lib: Allow using 0x when a decimal value is requested
U-Boot mostly uses hex for value input, largely because addresses are much
easier to understand in hex.
But in some cases a decimal value is requested, such as where the value is
small or hex does not make sense in the context. In these cases it is
sometimes useful to be able to provide a hex value in any case, if only to
resolve any ambiguity.
Add this functionality, for increased flexibility.

* For FSP1, the system memory and reserved memory used by FSP are

* The 'mtrr_top' mistakenly includes TSEG memory range that has the
same RES_MEM_RESERVED resource type. Its address is programmed

not what we want for SDRAM.
* The call to mtrr_add_request() is not guaranteed to have its size

sandbox: tpm: Correct handling of get-capability
This function current handles the kernel case incorrectly. Fix it, and
use the shorter TPM_HDR_LEN while we are here.

sandbox: tpm: Support the define-space command
Add support for this command, moving away from the previous approach of
hard-coding the initial data in the driver, now that the kernel-space data
has to be set up by the higher-level vboot code.

sandbox: tpm: Tidy up reading and writing of device state
At present this code assumes that the TPM data has been read but this may
not be the case. Refactor the code to use a separate pointer so we know
the current state of the data.
Add error checking for the data size.
