mach-sunxi: Add SPL SPI boot for SUNIV

2022-03-03T01:24:06Z

The SUNIV SoCs come with a sun6i-style SPI controller at the base address of sun4i SPI controller. The module clock of the SPI controller is missing which leaves us running directly from the AHB clock, which is set to 200MHz.

mach-sunxi: Add boot device detection for SUNIV/F1C100s

2022-03-03T01:23:58Z

In contrast to other Allwinner SoCs the F1C100s BROM does not store a boot source indicator in the eGON header in SRAM. This leaves the SPL guessing where we were exactly booted from, and for instance trying the SD card first, even though we booted from SPI flash. By inspecting the BROM code and by experimentation, Samuel found that the top of the BROM stack contains unique pointers for each of the boot sources, which we can use as a boot source indicator. This patch removes the existing board_boot_order bodge and replace it with a proper boot source indication function. The only caveat is that this only works in the SPL, as the SPL header gets overwritten with the exception vectors, once U-Boot proper takes over. Always return MMC0 as the boot source, when called from U-Boot proper, as a placeholder for now, until we find another way.

usb: ehci-omap: Drop dead code

2022-02-23T04:25:17Z

omap_ehci_hcd_stop appears to be dead code, and omap_ehci_hcd_init is only called by the probe function, so it can be static to that function. Remove both from the header along with some additional checking for DM_USB. Signed-off-by: Adam Ford

arm: omap3: Make some memory functions static and clean headers

2022-02-21T13:35:40Z

There are a few memory functions for both the emif4 (AM3517) and sdrc (OMAP35/DM37) code that can be defined as static, because those functions are not used externally. Make them static and clean up some of the corresponding headers. Signed-off-by: Adam Ford

arm: omap3: Cleanup sys_info to fit OMAP3 booting with LTO

2022-02-21T13:35:40Z

With LTO enabled, some functions appear to be optimized in a way that causes hanging on some OMAP3 boards after some unrelated patches were applied. The solution appears to make several functions __used. There also appears be to be some dead code, so remove it while cleaning this up. This has been tested on a general purpose OMAP3530, DM3730, and AM3517. Signed-off-by: Adam Ford

arm: apple: Add RTKit support

2022-02-10T21:44:23Z

Most Apple IOPs run a firmware that is based on what Apple calls RTKit. RTKit implements a common mailbox protocol. This code provides an implementation of the AP side of this protocol, providing a function to initialize RTKit-based firmwares as well as a function to do a clean shutdown of this firmware.

arm: apple: Change SoC name from "m1" into "apple"

2022-02-10T21:44:23Z

U-Boot is expected to support multiple generations of Apple SoCs in a single binary with a single defconfig. Therefore it makes more sense to set SYS_SOC to "apple". Signed-off-by: Mark Kettenis Reviewed-by: Simon Glass

Convert CONFIG_SCSI_AHCI_PLAT et al to Kconfig

This converts the following to Kconfig: CONFIG_SCSI_AHCI_PLAT CONFIG_SYS_SCSI_MAX_SCSI_ID CONFIG_SYS_SCSI_MAX_LUN CONFIG_SYS_SATA_MAX_DEVICE Drop CONFIG_SCSI for everything except the sandbox build. We only need one build for tests. Signed-off-by: Simon Glass Reviewed-by: Stefan Roese

scsi: Drop CONFIG_SYS_SCSI_MAX_DEVICE

This is defined based on two other CONFIGs for all boards except sandbox and durian. For sandbox the value does not matter. For durian the value seems excessive. Drop the option completely, to simplify configuration and reduce the number of things we need to convert to Kconfig. Signed-off-by: Simon Glass Reviewed-by: Stefan Roese
