2019-09-09efi_loader: check parameters EFI_FILE_PROTOCOL.GetInfo()Heinrich Schuchardt
Check the parameters of EFI_FILE_PROTOCOL.GetInfo() to avoid possible NULL dereference. Check the buffer size for EFI_FILE_SYSTEM_INFO. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-09efi_loader: volume name in EFI_FILE_PROTOCOL.GetInfo()Heinrich Schuchardt
We cannot determine the volume name in U-Boot. Instead of providing a dummy volume name in case of EFI_FILE_SYSTEM_INFO and EFI_UNSUPPORTED in case of EFI_FILE_SYSTEM_VOLUME_LABEL consistently return an empty string. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-09efi_loader: EFI_FILE_PROTOCOL rev 2 stubHeinrich Schuchardt
The UEFI specification requires to implement version 2 of the EFI_FILE_PROTOCOL. Provide the missing functions as stubs. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-09efi_loader: file size checksHeinrich Schuchardt
The file size has to be determined in multiple places. Factor out a common function. If on entry into EFI_FILE_PROTOCOL.Read() the current position is beyond the end of the file, return EFI_DEVICE_ERROR. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-09efi_loader: correct reading of directoriesHeinrich Schuchardt
EFI_FILE_PROTOCOL.Read() is used both to read files and directories. When reaching the end of a directory we always have to return buffer size zero irrespective of the incoming buffer size. (The described scenario for a Shim quirk cannot arise because every directory has at least '.' and '..' as entries.) Even when the buffer_size is too small multiple times we have to keep a reference to our last read directory entry. When we return to the start of the directory via SetPosition() we must remove the reference to a previously kept directory entry. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-09efi_loader: eliminate inline function ascii2unicode()Heinrich Schuchardt
ascii2unicode() can only convert characters 0x00-0x7f from UTF-8 to UTF-16. Use utf8_utf16_strcpy() instead. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-09-05efi_loader: EFI_BLOCK_IO_PROTOCOL.Reset()Heinrich Schuchardt
We cannot do anything in EFI_BLOCK_IO_PROTOCOL.Reset() but this does not justify to return an error. Let EFI_BLOCK_IO_PROTOCOL.Reset() return EFI_SUCCESS. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-05efi_loader: use EFI_PRINT() instead of debug()Heinrich Schuchardt
EFI_PRINT() offers indention of debug messages. Adjust the debug messages of the BLOCK_IO_PROTOCOL. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-09-05efi_loader: parameter checks BLOCK_IO_PROTOCOLHeinrich Schuchardt
Check parameters of ReadBlocks() and WriteBlocks(). If the buffer size is not a multiple of the block size, we have to return EFI_BAD_BUFFER_SIZE. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-08-11env: Drop the ACTION typedefSimon Glass
Avoid using a typedef here which is unnecessary. Add an 'env_' prefix to both the enum and its members to make it clear that these are related to the environment. Add an ENV prefix to these two flags so that it is clear what they relate to. Also move them to env.h since they are part of the public API. Use an enum rather than a #define to tie them together.

2019-08-11env: Drop the ENTRY typedefSimon Glass
U-Boot is not supposed to use typedef for structs anymore. Also this name is the same as the ENTRY() macro used in assembler files, and 'entry' itself is widely used in U-Boot (>8k matches).

2019-07-30efi_selftest: fix SetVirtualAddressMap unit testHeinrich Schuchardt
We read the address map before assigning the memory for the pages that will be mapped to virtual addresses. So these pages will overlap with the entry for EFI_CONVENTIONAL_MEMORY.

2019-07-30efi_loader: re-enable GRUB workaround on 32bit ARMHeinrich Schuchardt
GRUB on ARM 32bit prior to version 2.04 lacks proper handling of caches. In U-Boot v2019.04 a workaround for this was inadvertently removed. The workaround is currently also needed for booting on systems with caches that cannot be managed via CP15 (e.g. with an i.MX6 CPU). Re-enable the workaround and make it customizable.
