2024-12-27spl: Drop use of uintptr_tSimon Glass
U-Boot uses ulong for addresses. It is confusing to use uintptr_t in a few places, since it makes people wonder if the types are compatible. Change the few occurences in SPL to use ulong Signed-off-by: Simon Glass <[email protected]>

2022-10-31Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASESimon Glass
The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE and this makes it imposible to use CONFIG_VAL(). Rename it to resolve this problem. Signed-off-by: Simon Glass <[email protected]>

2020-12-04spl: atf: remove helper structure from common headerMichael Walle
bl2_to_bl31_params_mem is just an implementation detail of the SPL ATF support and is not needed anywhere else. Move it from the header to the actual module. Signed-off-by: Michael Walle <[email protected]> Acked-by: Michal Simek <[email protected]>
2020-12-04spl: atf: provide a bl2_plat_get_bl31_params_default()Michael Walle
Move the actual implementation of the bl2_plat_get_bl31_params() to its own function. The weak function will just call the default implementation. This has the advantage that board code can still call the original implementation if it just want to modify minor things. Signed-off-by: Michael Walle <[email protected]>
2020-12-04spl: atf: move storage for bl31_params into functionMichael Walle
There is no need to have the storage available globally. This is also a preparation for LOAD_IMAGE_V2 support. That will introduce a similar generator function which also has its own storage. Signed-off-by: Michael Walle <[email protected]> Acked-by: Michal Simek <[email protected]>
2020-10-27spl: Use standard FIT entriesMichal Simek
SPL is creating fit-images DT node when loadables are recorded in selected configuration. Entries which are created are using entry-point and load-addr property names. But there shouldn't be a need to use non standard properties because entry/load are standard FIT properties. But using standard FIT properties enables option to use generic FIT functions to descrease SPL size. Here is result for ZynqMP virt configuration: xilinx_zynqmp_virt: spl/u-boot-spl:all -82 spl/u-boot-spl:rodata -22 spl/u-boot-spl:text -60 The patch causes change in run time fit image record. Before: fit-images { uboot { os = "u-boot"; type = "firmware"; size = <0xfd520>; entry-point = <0x8000000>; load-addr = <0x8000000>; }; }; After: fit-images { uboot { os = "u-boot"; type = "firmware"; size = <0xfd520>; entry = <0x8000000>; load = <0x8000000>; }; }; Replacing calling fdt_getprop_u32() by fit_image_get_entry/load() also enables support for reading entry/load properties recorded in 64bit format.

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 <[email protected]>
2020-01-14spl: atf: Enable option to rewrite bl2_plat_get_bl31_params()Michal Simek

2020-01-14spl: atf: Add missing ndepth initializationMichal Simek
ndepth needs to be initialized before it is used in fdt_next_node(). Uninitialized value is causing that node is found and depth increase but won't pass condition below because initial state wasn't setup. Signed-off-by: Michal Simek <[email protected]>
2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass
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 <[email protected]> Reviewed-by: Tom Rini <[email protected]>
2019-11-10common: spl: atf: support booting bl32 imageJoseph Chen
Trusted-Firmware can also initialize a secure payload to use as a trusted execution environment. In general for the arm64 case this is provided as separate image and uboot is supposed to also place it in a predetermined location in memory and add the necessary parameters to the ATF boot params. So add the possibility to get this tee payload from the provided FIT image and setup things as necessary. Tested on a Rockchip PX30 with mainline TF-A, mainline OP-Tee (with pending PX30 support) and mainline 5.4-rc1 Linux kernel.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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 <[email protected]>

2018-01-03spl: atf: add SPL_ATF_NO_PLATFORM_PARAM optionPhilipp Tomsich
While we expect to call a pointer to a valid FDT (or NULL) as the platform parameter to an ATF, some ATF versions are not U-Boot aware and have an insufficiently robust (or an overzealour) parameter validation: either way, this may cause a hard-stop with uncooperative ATF versions. This change adds the option to suppress passing a platform parameter and will always pass NULL. Debug output from ATF w/ this option disabled (i.e. default): INFO: plat_param_from_bl2: 0x291450 Debug output from ATF w/ this option enabled: INFO: plat_param_from_bl2: 0 Signed-off-by: Philipp Tomsich <[email protected]> Tested-by: Philipp Tomsich <[email protected]> Reviewed-by: Kever Yang <[email protected]>
2017-11-26spl: atf: introduce spl_invoke_atf and make bl31_entry privatePhilipp Tomsich
This adds a new interface spl_invoke_atf() that takes a spl_image_info argument and then derives the necessary parameters for the ATF entry. Based on the additional information recorded (into /fit-images) from the FIT loadables, we can now easily locate the next boot stage. We now pass a pointer to a FDT as the platform-specific parameter pointer to ATF (so we don't run into the future headache of every board/platform defining their own proprietary tag-structure), as FDT access is already available in ATF. With the necessary infrastructure in place, we can now update the support for the ARM Trusted Firmware to dispatch into the spl_invoke_atf function only if a IH_OS_ARM_TRUSTED_FIRMWARE image is loaded.

2017-05-15spl: add support to booting with ATFKever Yang
ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation about ATF at: https://github.com/ARM-software/arm-trusted-firmware SPL is considered as BL2 in ATF terminology, it needs to load other parts of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to prepare the parameter for BL31 which including entry and image information for all other images. Then the SPL handle PC to BL31 with the parameter, the BL31 will do the rest of work and at last get into U-Boot(BL33). This patch needs work with patches from Andre for SPL support multi binary in FIT. The entry point of bl31 and bl33 are still using hard code because we still can not get them from the FIT image information.
