* command: Remove the cmd_tbl_t typedefSimon Glass2020-05-182-2/+3
| | | | | | | | | | | | | We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

* common: Drop net.h from common headerSimon Glass2020-05-181-0/+1
| | | | | | | | | | | Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
* common: Move hang() to the same header as panic()Simon Glass2020-01-171-0/+1
| | | | | | | | | | At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: Migrate a few more files] Signed-off-by: Tom Rini <trini@konsulko.com>
* common: Move interrupt functions into a new headerSimon Glass2019-12-021-0/+1
| | | | | | | | | | | | These functions do not use driver model but are fairly widely used in U-Boot. But it is not clear that they will use driver model anytime soon, so we don't want to label them as 'legacy'. Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it is widely used in U-Boot already. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
* common: Move some cache and MMU functions out of common.hSimon Glass2019-12-021-0/+1
| | | | | | | | | | | | These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

* microblaze: Convert generic platform to DM gpioMichal Simek2018-07-191-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Converting GPIO to DM requires to do changes in reset subsystem that's why support for Microblaze soft reset via sysreset and GPIO sysreset support was added. These two patches enables enabling GPIO DM. Microblaze soft reset is bind at last reset method. GPIO reset is handled via sysreset with adding this fragment to DT. gpio-restart { compatible = "gpio-restart"; gpios = <&reset_gpio 0 0 0>; /* 3rd cell ACTIVE_HIGH = 0, ACTIVE_LOW = 1 */ }; hard-reset-gpio property is not documented and also handled. Conversion is required. Unfortunately do_reset is required for SPL that's why use only soft microblaze reset for now. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
* microblaze: Do not call timer init that earlyMichal Simek2018-07-191-0/+4
| | | | | | | | | | Timer needs to be converted to DM but as of now it can't be called so early because intc controller is not ready. Call it later in board_r.c. Before this patch timer_init is called twice which is wrong. The patch is blocking initialization before relocation.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-0710-21/+10
| | | | | | | | | | | | | | | | | | | | 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>

* microblaze: spl: configure SYS_MALLOC_F_LEN independently for SPL and full ↵Andy Yan2017-07-271-4/+4
| | | | | | | | | | | | | | | | | | U-Boot Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.

* spl: make image arg or fdt blob address reconfigurableVikas Manocha2017-05-081-3/+3
| | | | | | | | | | | At present fdt blob or argument address being passed to kernel is fixed at compile time using macro CONFIG_SYS_SPL_ARGS_ADDR. FDT blob from different media like nand, nor flash are copied to the address pointed by the macro. The problem is, it makes args/fdt blob compulsory to copy which is not required in cases like for NOR Flash. This patch removes this limitation. Signed-off-by: Vikas Manocha <vikas.manocha@st.com>
