lib: Remove inclusion from these files

2023-12-21T13:54:37+00:00

After some header file cleanups to add missing include files, remove
common.h from all files in the lib directory. This primarily means just
dropping the line but in a few cases we need to add in other header
files now.

cyclic: Use schedule() instead of WATCHDOG_RESET()

2022-09-18T08:26:33+00:00

Globally replace all occurances of WATCHDOG_RESET() with schedule(),
which handles the HW_WATCHDOG functionality and the cyclic
infrastructure.

crc32: Add crc32 implementation using __builtin_aarch64_crc32b

2021-09-23T18:15:32+00:00

ARMv8.0 has optional crc32 instruction for crc32 calculation. The
instruction is mandatory since ARMv8.1. The crc32 calculation is
faster using the dedicated instruction, e.g. 1.4 GHz iMX8MN gives:

  => time crc32 0x50000000 0x2000000
  time: 0.126 seconds # crc32 instruction
  time: 0.213 seconds # software crc32

Add implementation using the compiler builtin wrapper for the crc32
instruction and enable it by default, since we don't support any
platforms which do not implement this instruction.

lib: crc32: put the crc_table variable into efi_runtime_rodata section

2021-05-24T18:21:30+00:00

When compiling with LTO, the compiler fails with an error saying that
`crc_table` causes a section type conflict with `efi_var_buf`.

This is because both are declared to be in the same section (via macro
`__efi_runtime_data`), but one is const while the other is not.

Put this variable into the section .rodata.efi_runtime, instead of
.data.efi_runtime, via macro __efi_runtime_rodata.

crc32: Use the crc.h header for crc functions

2019-12-02T23:23:08+00:00

Drop inclusion of crc.h in common.h and use the correct header directly
instead.

With this we can drop the conflicting definition in fw_env.h and rely on
the crc.h header, which is already included.

crc: Fix code style with crc functions

2019-12-02T23:23:07+00:00

Some of these have a space before the bracket. Drop it to fix the style.
Add some missing function comments while here.

Note that u32 and u8 cannot be used here since crc.h is included on the
host side.

lib: crc32: mark static variable as __efi_runtime_data

2018-12-23T01:39:52+00:00

In commit 483dbab9f931 ("lib: crc32: mark function crc32() as
__efi_runtime") one local static variable was missed. It did not end up in
the __efi_runtime_data section as it should.

If CONFIG_DYNAMIC_CRC_TABLE=y a data abort execption may occur when the
UEFI payload calls the SetVirtualAddressMap() runtime service.

lib: crc32: mark function crc32() as __efi_runtime

2018-08-20T12:42:36+00:00

The function crc32() is needed by the EFI subsystem at runtime. So it has
to be linked into the runtime section together with all dependencies.

Eliminate empty defines local and ZEXPORT.

Mark variables as static which are not exported.
