2019-12-03cmd: efidebug: fix a build error in show_efi_boot_opt()AKASHI Takahiro
I detected the following error in sandbox with Clang on Travis CI: +cmd/efidebug.c:703:15: error: result of comparison of constant 9223372036854775822 with expression of type 'int' is always false [-Werror,-Wtautological-constant-out-of-range-compare] + else if (ret == EFI_NOT_FOUND) + ~~~ ^ ~~~~~~~~~~~~~ Simply changing a type of 'ret' to efi_status_t will fix this error.

2019-05-02efi_loader: optional data in load options are binaryHeinrich Schuchardt
The field boot OptionalData in structure _EFI_LOAD_OPTIONS is for binary data. When we use `efidebug boot add` we should convert the 5th argument from UTF-8 to UTF-16 before putting it into the BootXXXX variable. When printing boot variables with `efidebug boot dump` we should support the OptionalData being arbitrary binary data. So let's dump the data as hexadecimal values. Here is an example session protocol: => efidebug boot add 00a1 label1 scsi 0:1 doit1 'my option' => efidebug boot add 00a2 label2 scsi 0:1 doit2 => efidebug boot dump Boot00A0: attributes: A-- (0x00000001) label: label1 file_path: .../HD(1,MBR,0xeac4e18b,0x800,0x3fffe)/doit1 data: 00000000: 6d 00 79 00 20 00 6f 00 70 00 74 00 69 00 6f 00 m.y. .o.p.t.i.o. 00000010: 6e 00 00 00 n...

2019-05-02cmd: efidebug: rework "boot dump" sub-command using GetNextVariableName()AKASHI Takahiro
Currently in do_efi_boot_dump(), we directly read EFI variables from related environment variables. To accommodate alternative storage backends, we should switch to using the UEFI API instead.

2019-04-23efi_loader: more short texts for protocols in efidebugHeinrich Schuchardt
The `efidebug dh` command shows handles and the installed protocols. For most of the protocols implemented by U-Boot a short text was shown. But for some only the GUID was displayed. Provide the missing short texts for the following protocols: HII String, HII Database, HII Config Routing, Simple Network, PXE Base Code. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-04-23efi_loader: consistent naming of protocol GUIDsHeinrich Schuchardt
We should consistently use the same name for protocol GUIDs as defined in the UEFI specification. Not adhering to this rule has led to duplicate definitions for the EFI_LOADED_IMAGE_PROTOCOL_GUID. Adjust misnamed protocol GUIDs. Adjust the text for the graphics output protocol in the output of the `efidebug dh` command. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-03-02efi_loader: error handling for `efidebug boot add`Heinrich Schuchardt
In `efidebug boot add iPXE scsi 0:1 snp-arm64.efi --foo` a parameter is missing. Hence the command should not silently return as if everything were ok but should display the usage info. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Alexander Graf <agraf@csgraf.de>

2019-02-25cmd: add efidebug commandAKASHI Takahiro
Currently, there is no easy way to add or modify UEFI variables. In particular, bootmgr supports BootOrder/BootXXXX variables, it is quite hard to define them as u-boot variables because they are represented in a complicated and encoded format. The new command, efidebug, helps address these issues and give us more friendly interfaces: * efidebug boot add: add BootXXXX variable * efidebug boot rm: remove BootXXXX variable * efidebug boot dump: display all BootXXXX variables * efidebug boot next: set BootNext variable * efidebug boot order: set/display a boot order (BootOrder) Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
