2022-02-25clk: Add driver API to HTML docsSean Anderson
This converts the existing driver API docs (clk-uclass.h) to kernel doc format and adds them to the HTML documentation. Because the kernel doc sphinx converter does not handle functions in structs very well, the individual methods are documented separately. This is primarily inspired by the phylink documentation [1], which uses this trick extensively.

2020-12-18linker_lists: Fix alignment issueSimon Glass
The linker script uses alphabetic sorting to group the different linker lists together. Each group has its own struct and potentially its own alignment. But when the linker packs the structs together it cannot ensure that a linker list starts on the expected alignment boundary. For example, if the first list has a struct size of 8 and we place 3 of them in the image, that means that the next struct will start at offset 0x18 from the start of the linker_list section. If the next struct has a size of 16 then it will start at an 8-byte aligned offset, but not a 16-byte aligned offset. With sandbox on x86_64, a reference to a linker list item using ll_entry_get() can force alignment of that particular linker_list item, if it is in the same file as the linker_list item is declared. Consider this example, where struct driver is 0x80 bytes: ll_entry_declare(struct driver, fred, driver) ... void *p = ll_entry_get(struct driver, fred, driver) If these two lines of code are in the same file, then the entry is forced to be aligned at the 'struct driver' alignment, which is 16 bytes. If the second line of code is in a different file, then no action is taken, since the compiler cannot update the alignment of the linker_list item. In the first case, an 8-byte 'fill' region is added: .u_boot_list_2_driver_2_testbus_drv 0x0000000000270018 0x80 test/built-in.o 0x0000000000270018 _u_boot_list_2_driver_2_testbus_drv .u_boot_list_2_driver_2_testfdt1_drv 0x0000000000270098 0x80 test/built-in.o 0x0000000000270098 _u_boot_list_2_driver_2_testfdt1_drv *fill* 0x0000000000270118 0x8 .u_boot_list_2_driver_2_testfdt_drv 0x0000000000270120 0x80 test/built-in.o 0x0000000000270120 _u_boot_list_2_driver_2_testfdt_drv .u_boot_list_2_driver_2_testprobe_drv 0x00000000002701a0 0x80 test/built-in.o 0x00000000002701a0 _u_boot_list_2_driver_2_testprobe_drv With this, the linker_list no-longer works since items after testfdt1_drv are not at the expected address. Ideally we would have a way to tell gcc not to align structs in this way. It is not clear how we could do this, and in any case it would require us to adjust every struct used by the linker_list feature. One possible fix is to force each separate linker_list to start on the largest possible boundary that can be required by the compiler. However that does not seem to work on x86_64, which uses 16-byte alignment in this case but needs 32-byte alignment. So add a Kconfig option to handle this. Set the default value to 4 so as to avoid changing platforms that don't need it. Update the ll_entry_start() accordingly. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-10-30lib: Add getoptSean Anderson
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>

2020-07-11efi_loader: prepare for read only OP-TEE variablesHeinrich Schuchardt
We currently have two implementations of UEFI variables: * variables provided via an OP-TEE module * variables stored in the U-Boot environment Read only variables are up to now only implemented in the U-Boot environment implementation.
