include/u-boot, lib/zlib: add sources for zlib decompression

2020-08-08T02:31:32+00:00

Add zlib (v1.2.11) uncompr() function to U-Boot. SquashFS depends on
this function to decompress data from a raw disk image. The actual
support for zlib into SquashFS sources will be added in a follow-up
commit.

lmb/bdinfo: dump lmb info via bdinfo

2020-08-05T03:30:02+00:00

Dump lmb status from the bdinfo command. This is useful for seeing the
reserved memory regions from the u-boot cmdline.

efi: Tidy up header includes

2020-08-04T02:19:54+00:00

Two files relies on efi_driver.h to include common.h and dm.h which is
incorrect. The former should always be included in a non-host C file and
the latter should be included if driver model is used.

efi_selftest: block device test requires CONFIG_DOS_PARTITION

2020-08-01T09:58:39+00:00

Do not execute the block device test if CONFIG_DOS_PARTITION=n.

Imply CONFIG_DOS_PARTITION in Kconfig.

If CONFIG_NET=n, testing the simple network protocol makes no sense.

efi_loader: use CONFIG_STACK_SIZE in the UEFI sub-system

2020-08-01T09:58:23+00:00

The Kconfig symbol CONFIG_STACK_SIZE is used both by ARM and Microblaze
with the same meaning. Move it to menu 'General setup' so that we can use
it for all architectures.

Use the value of CONFIG_STACK_SIZE instead of a hard coded 16 MiB value for
reserving memory in the UEFI sub-system.

efi_loader: Enable run-time variable support for tee based variables

2020-08-01T09:57:41+00:00

We recently added functions for storing/restoring variables
from a file to a memory backed buffer marked as __efi_runtime_data
commit f1f990a8c958 ("efi_loader: memory buffer for variables")
commit 5f7dcf079de8 ("efi_loader: UEFI variable persistence")

Using the same idea we now can support GetVariable() and GetNextVariable()
on the OP-TEE based variables as well.

So let's re-arrange the code a bit and move the commmon code for
accessing variables out of efi_variable.c. Create common functions for
reading variables from memory that both implementations can use on
run-time. Then just use those functions in the run-time variants of the
OP-TEE based EFI variable implementation and initialize the memory
buffer on ExitBootServices()

efi_loader: Trim output buffer size correctly for tee variables

2020-08-01T09:57:41+00:00

The current code does not trim the output buffer correctly.
In fact it doesn't trim the buffer at all, since it calculates a wrong
value for it, which isn't even applied.
So let's remove the unused temporary size variable and trim the buffer
correctly.
Since we are editing efi_get_next_variable_name_int(), fix an indentation
error along the way.

env: Add support for explicit write access list

2020-07-31T14:13:00+00:00

This option marks any U-Boot variable which does not have explicit 'w'
writeable flag set as read-only. This way the environment can be locked
down and only variables explicitly configured to be writeable can ever
be changed by either 'env import', 'env set' or loading user environment
from environment storage.

env: Add option to only ever append environment

2020-07-31T14:13:00+00:00

Add configuration option which prevents the environment hash table to be
ever cleared and reloaded with different content. This is useful in case
the first environment loaded into the hash table contains e.g. sensitive
content which must not be dropped or reloaded.
