* efi_loader: parameter checks BLOCK_IO_PROTOCOLHeinrich Schuchardt2019-09-051-1/+36
| | | | | | | | | 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>
* efi_loader: do not set invalid screen modeHeinrich Schuchardt2019-09-051-0/+4

* efi_loader: cursor positioningHeinrich Schuchardt2019-09-051-5/+13
| | | | | | | | | | When backspacing in column 0 do no set the column index to ULONG_MAX. Ensure that the row number is not set to ULONG_MAX even if the row count is advertised as 0. Ignore control characters other the 0x08, 0x0a, 0x0d when updating the column. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

| | | | | | | | | | | | | Commit 7f95104d91cc ("efi_loader: detach runtime in ExitBootServices()") added a call to efi_runtime_detach() to ExitBootServices() but did not remove the call in SetVirtualAddressMap().

| | | | | | | | | | | | U-Boot implements the EFI_PXE_BASE_CODE_PROTOCOL because GRUB uses the mode information for booting via PXE. All function pointers in the protocol were NULL up to now which will cause immediate crashes when the services of the protocol are called. Create function stubs for all services of the protocol returning EFI_UNSUPPORTED. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

* efi_loader: re-enable GRUB workaround on 32bit ARMHeinrich Schuchardt2019-07-302-15/+21
| | | | | | | | | | | | | 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.

* efi_loader: Change return type of efi_add_memory_map()Bryan O'Donoghue2019-07-162-15/+23
| | | | | | | | | | | | | | | | | | | | | | | | We currently have some inconsistent use of efi_add_memory_map() throughout the code. In particular the return value of efi_add_memory_map() is not interpreted the same way by various users in the codebase. This patch does the following: - Changes efi_add_memory_map() to return efi_status_t. - Adds a method description to efi_add_memory_map(). - Changes efi_add_memory_map() to return EFI_SUCCESS - Returns non-zero for error in efi_add_memory_map() - Updates efi_allocate_pages() to new efi_add_memory_map() - Updates efi_free_pages() to new efi_add_memory_map() - Updates efi_carve_out_dt_rsv() to new efi_add_memory_map() - Updates efi_add_runtime_mmio() to new efi_add_memory_map() Fixes: 5d00995c361c ("efi_loader: Implement memory allocation and map") Fixes: 74c16acce30b ("efi_loader: Don't allocate from memory holes") Suggested-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Cc: Alexander Graf <agraf@csgraf.de> Signed-off-by: Bryan O'Donoghue <pure.logic@nexus-software.ie> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

In this case SetVirtualAddressMap() is not called after ExitBootServices(). OpenBSD 32bit does not call SetVirtualAddressMap() either.

* efi_loader: clean up runtime detachingHeinrich Schuchardt2019-07-061-23/+55
| | | | | | | | | | | The detaching of the runtime will have to move to ExitBootServices() to encompass operating system that do not call SetVirtualAddressMap().
