2025-06-13spl: Rename jump_to_image_no_args()Simon Glass
This function is currently a misnomer at times as we have cases where it passes arguments to the image. In preparation for making that be a more common case rename this function to jump_to_image(...). In order to do this, rename jump_to_image in board_init_r(...) to jumper so that we do not have a conflict.

2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2021-03-26x86: Support a fake PCI device with of-platdata-instSimon Glass
With TPL we don't need full PCI support and it adds to code size. Instead, a simple_bus driver is good enough to be able to read and write the PCI config and do a little basic setup. So at present there are two drivers in U-Boot called pci_x86. One is in UCLASS_PCI, used in SPL and U-Boot proper. The other is in UCLASS_SIMPLE_BUS and used only in TPL. Add a tag to tell dtoc about this, so it knows which one to use when generating the devices and uclasses. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-11-06x86: Use CONFIG_CHROMEOS_VBOOT for verified bootSimon Glass
At present CONFIG_CHROMEOS is used to determine whether verified boot is in use. The code to implement that is not in U-Boot mainline. However, it is useful to be able to boot a Chromebook in developer mode in U-Boot mainline without needing the verified boot code. To allow this, use CONFIG_CHROMEOS_VBOOT to indicate that verified boot should be used, and CONFIG_CHROMEOS to indicate that the board supports Chrome OS. That allows us to define CONFIG_CHROMEOS on coral. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2020-01-17common: Move hang() to the same header as panic()Simon Glass
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.

2019-11-03x86: Move CPU init to before spl_init()Simon Glass
At present we call spl_init() before identifying the CPU. This is not a good idea - e.g. if bootstage is enabled then it will try to set up the timer which works better if the CPU is identified. Put explicit code at each entry pointer to identify the CPU. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2019-11-03x86: tpl: Add a fake PCI busSimon Glass
In TPL we try to minimise code size so do not include the PCI subsystem. We can use fixed BARs and drivers can directly program the devices that they need. However we do need to bind the devices on the PCI bus and without PCI this does not ordinarily happen. As a work-around, define a fake PCI bus which does this binding, but no other PCI operations. This is a convenient way to ensure that we can use the same device tree for TPL, SPL and U-Boot proper: TPL - CONFIG_TPL_PCI is not set (no auto-config, fake PCI bus) SPL - CONFIG_SPL_PCI is set (no auto-config but with real PCI bus) U-Boot - CONFIG_PCI is set (full auto-config after relocation) Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2019-10-08x86: spl: Reduce priority of the basic SPL image loaderSimon Glass
This image loader works on systems where the flash is directly mapped to the last part of the 32-bit address space. On recent Intel systems (such as apollolake) this is not the case. Reduce the priority of this loader so that another one can override it. While we are here, rename the loader to BOOT_DEVICE_SPI_MMAP since BOOT_DEVICE_BOARD is not very descriptive.
