cmd: bootefi: Parse reserved-memory node from DT

2020-03-17T07:29:52+00:00

Currently, bootefi only parses memory reservation block to setup
EFI reserved memory mappings. However, it doesn't parse the
reserved-memory[1] device tree node that also can contain the
reserved memory regions.

Add capability to parse reserved-memory node and update the EFI memory
mappings accordingly.

Fix an endless loop.

The /reserved-memory node may have children without reg property. Remove
a superfluous debug statement.

cmd: map addresses to sysmem in efidebug memmap

2020-03-17T07:29:52+00:00

Addresses in the sandbox's device tree are in the sandbox's virtual address
space. If we want to compare memory reservations in the device-tree with
the output of 'efidebug memmap', we need to convert back to this address
space.

Adjust the output of the 'efidebug memmap' command.

efi_loader: create reservations after ft_board_setup

2020-03-17T07:29:52+00:00

Some memory reservations are made in ft_board_setup(). Ensure that we
create reserved memory map entries after ft_board_setup().

The downside of this patch is that if bootefi is called multiple times with
an devicetree argument superfluous reservations for the old copies of the
device tree will exist. But that is still better than missing a reservation.

Deleting the superfluous reservations is not possible because reservations
in the memory map are rounded to page size and may be coallesced.

cmd: gpio: Make `gpio input` return pin value again

2020-03-13T13:30:30+00:00

4dbc107f4683 ("cmd: gpio: Correct do_gpio() return value") correctly
changed the behaviour of the gpio command to return CMD_RET_SUCCESS or
CMD_RET_FAILURE, but any existing script which expects the return value
to be the pin value is broken by this change.

Reinstate the legacy behaviour for `gpio input` only.

cmd: efidebug: correct error message

2020-03-11T07:23:05+00:00

Add the missing line feed at the error message if the variable referred to
by 'efidebug boot rm' does not exist.

Shorten the format string by using the variable name instead of the number
of the boot variable.

cmd: efidebug: fix a failure of "boot rm" sub-command

2020-03-11T07:23:05+00:00

There is a wrong usage of utf8_utf16_strncpy() in "boot rm" command, and
then it will end up with a failure of this command due to a wrong
value of an interim variable ("var_name16").

efi_loader: Implement FileLoad2 for initramfs loading

2020-02-28T18:37:14+00:00

Following kernel's proposal for an arch-agnostic initrd loading
mechanism [1] let's implement the U-boot counterpart.
This new approach has a number of advantages compared to what we did up
to now. The file is loaded into memory only when requested limiting the
area of TOCTOU attacks. Users will be allowed to place the initramfs
file on any u-boot accessible partition instead of just the ESP one.
Finally this is an attempt of a generic interface across architectures
in the linux kernel so it makes sense to support that.

The file location is intentionally only supported as a config option
argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security.
Although U-boot is not responsible for verifying the integrity of the
initramfs, we can enhance the offered security by only accepting a
built-in option, which will be naturally verified by UEFI Secure Boot.
This can easily change in the future if needed and configure that via ENV
or UEFI variable.

efi_loader: implement EFI_RT_PROPERTIES_TABLE

UEFI spec 2.8 errata A replaces the RuntimeServicesSupported variable
defined in UEFI spec 2.8 by the configuration table
EFI_RT_PROPERTIES_TABLE. So let's follow suit.
