2017-10-29efi_loader: Disable env_save() call on bootAlexander Graf
With the introduction of EFI variable support, we also wanted to persist these EFI variables. However, the way it was implemented we ended up persisting all U-Boot environment variables on every EFI boot. That could potentially lead to unexpected side effects because variables that were not supposed to be written to persisted env get written. It also means we may end up writing the environment more often than we should. For this release, let's just disable EFI variable persistence and instead implement it properly for the next one.

2017-10-12efi_loader: console support for color attributesRob Clark
Shell.efi uses this, and supporting color attributes makes things look nicer. Map the EFI fg/bg color attributes to ANSI escape sequences.

When searching for partitions don't stop if a partition is not present for a given partition number as there may be valid partitions after. Search for up to MAX_SEARCH_PARTITIONS matching the other callers of part_get_info(). This allows OpenBSD to boot via the efi_loader on rpi_3 again after changes made after U-Boot 2017.09.

2017-09-20efi_loader: add bootmgrRob Clark
Similar to a "real" UEFI implementation, the bootmgr looks at the BootOrder and BootXXXX variables to try to find an EFI payload to load and boot. This is added as a sub-command of bootefi. The idea is that the distro bootcmd would first try loading a payload via the bootmgr, and then if that fails (ie. first boot or corrupted EFI variables) it would fallback to loading bootaa64.efi. (Which would then load fallback.efi which would look for \EFI\*\boot.csv and populate BootOrder and BootXXXX based on what it found.)

2017-09-20efi_loader: efi variable supportRob Clark
Add EFI variable support, mapping to u-boot environment variables. Variables are pretty important for setting up boot order, among other things. If the board supports saveenv, then it will be called in ExitBootServices() to persist variables set by the efi payload. (For example, fallback.efi configuring BootOrder and BootXXXX load-option variables.) Variables are *not* currently exposed at runtime, post ExitBootServices. On boards without a dedicated device for storage, which the loaded OS is not trying to also use, this is rather tricky. One idea, at least for boards that can persist RAM across reboot, is to keep a "journal" of modified variables in RAM, and then turn halt into a reboot into u-boot, plus store variables, plus halt. Whatever the solution, it likely involves some per-board support. Mapping between EFI variables and u-boot variables: efi_$guid_$varname = {attributes}(type)value For example: efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_OsIndicationsSupported= "{ro,boot,run}(blob)0000000000000000" efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_BootOrder= "(blob)00010000" The attributes are a comma separated list of these possible attributes: + ro - read-only + boot - boot-services access + run - runtime access NOTE: with current implementation, no variables are available after ExitBootServices, and all are persisted (if possible). If not specified, the attributes default to "{boot}".
