* smbios: add parsing APIChristian Gmeiner2020-11-051-0/+1

* lib: Add getoptSean Anderson2020-10-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some commands can get very unweildy if they have too many positional arguments. Adding options makes them easier to read, remember, and understand. This implementation of getopt has been taken from barebox, which has had option support for quite a while. I have made a few modifications to their version, such as the removal of opterr in favor of a separate getopt_silent function. In addition, I have moved all global variables into struct getopt_context. The getopt from barebox also re-orders the arguments passed to it so that non-options are placed last. This allows users to specify options anywhere. For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as getopt parsed the options. However, this feature conflicts with the const argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure that argv[] argument pointers are not modified."). The reason stated in that commit is that hush requires argv to stay unmodified. Has this situation changed? Barebox also uses hush, and does not have this problem. Perhaps we could use their fix? I have assigned maintenance of getopt to Simon Glass, as it is currently only used by the log command. I would also be fine maintaining it. Signed-off-by: Sean Anderson <seanga2@gmail.com>

* Add support for SHA384 and SHA512Reuben Dowle2020-06-121-0/+1
| | | | | | | | | | | | | | | | The current recommendation for best security practice from the US government is to use SHA384 for TOP SECRET [1]. This patch adds support for SHA384 and SHA512 in the hash command, and also allows FIT images to be hashed with these algorithms, and signed with sha384,rsaXXXX and sha512,rsaXXXX The SHA implementation is adapted from the linux kernel implementation.

* initcall: Move to inline functionAlexander Graf2019-02-091-1/+0
| | | | | | | | | | | | | | | The board_r init function was complaining that we are looping through an array, calling all our tiny init stubs sequentially via indirect function calls (which can't be speculated, so they are slow). The solution to that is pretty easy though. All we need to do is inline the function that loops through the functions and the compiler will automatically convert almost all indirect calls into direct inlined code. With this patch, the overall code size drops (by 40 bytes on riscv64) and boot time should become measurably faster for every target. Signed-off-by: Alexander Graf <agraf@suse.de>

Current drivers are currently prefixed by "tpm_", we will prefix TPMv2.x files by "tpm2_" to make the distinction without moving everything. The Kconfig menu about TPM drivers is now divided into two sections, one for each specification. Compliant drivers with one specification will only show up if this specification _only_ has been selected, otherwise a comment is displayed. Once a driver is selected by the user, it selects automatically a boolean value, that is needed in order to activate the TPM commands. Selecting the TPM commands will automatically select the right command/library files.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-3/+1
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides * a uclass for EFI drivers * a EFI driver for block devices For each EFI driver the uclass * creates a handle * adds the driver binding protocol The uclass provides the bind, start, and stop entry points for the driver binding protocol. In bind() and stop() it checks if the controller implements the protocol supported by the EFI driver. In the start() function it calls the bind() function of the EFI driver. In the stop() function it destroys the child controllers. The EFI block driver binds to controllers implementing the block io protocol. When the bind function of the EFI block driver is called it creates a new U-Boot block device. It installs child handles for all partitions and installs the simple file protocol on these. The read and write functions of the EFI block driver delegate calls to the controller that it is bound to. A usage example is as following: U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and exposes a handle with the block IO protocol. It calls ConnectController. Now the EFI block driver installs the partitions with the simple file protocol. iPXE uses the simple file protocol to load Grub or the Linux Kernel.

* efi_selftest: provide an EFI selftest applicationHeinrich Schuchardt2017-09-181-0/+1
| | | | | | | | | | | | | | | | | | | | | A testing framework for the EFI API is provided. It can be executed with the 'bootefi selftest' command. It is coded in a way that at a later stage we may turn it into a standalone EFI application. The current build system does not allow this yet. All tests use a driver model and are run in three phases: setup, execute, teardown. A test may be setup and executed at boottime, it may be setup at boottime and executed at runtime, or it may be setup and executed at runtime. After executing all tests the system is reset.

| | | | | | | | | | | This splits the compilation of code modules for TPL and SPL for OF_CONTROL (and related) features between TPL and SPL. The typical use-case of this is a TPL stage that uses OF_PLATDATA at TPL and provides full OF_CONTROL at SPL (e.g. on the RK3368).
