* sunxi: A64: do an RMR switch if started in AArch32 modeAndre Przywara2017-01-04-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The Allwinner A64 SoC starts execution in AArch32 mode, and both the boot ROM and Allwinner's boot0 keep running in this mode. So U-Boot gets entered in 32-bit, although we want it to run in AArch64. By using a "magic" instruction, which happens to be an almost-NOP in AArch64 and a branch in AArch32, we differentiate between being entered in 64-bit or 32-bit mode. If in 64-bit mode, we proceed with the branch to reset, but in 32-bit mode we trigger an RMR write to bring the core into AArch64/EL3 and re-enter U-Boot at CONFIG_SYS_TEXT_BASE. This allows a 64-bit U-Boot to be both entered in 32 and 64-bit mode, so we can use the same start code for the SPL and the U-Boot proper. We use the existing custom header (boot0.h) functionality, but restrict the existing boot0 header reservation to the non-SPL build now. A SPL wouldn't need such header anyway. This allows to have both options defined and lets us use one for the SPL and the other for U-Boot proper. Also add arch/arm/mach-sunxi/rmr_switch.S, which contains the original ARM assembly code and instructions how to re-generate the encoded version.

* ARM: boot0 hook: remove macro, include whole header fileAndre Przywara2017-01-04-21/+3
| | | | | | | | | | | | | | | | | | For prepending some board specific header area to U-Boot images we were so far including a header file with a macro definition containing the actual header specification. This works fine if there are just a few statements and if there is only one alternative. However adding more complex code quickly gets messy with this approach, so let's just drop that intermediate macro and let the #include actually insert the code directly. This converts the callers and the callees, but doesn't change anything at this point.

* armv8: move reset branch into boot hookAndre Przywara2017-01-04-0/+1
| | | | | | | | | | | | | The boot0 hook we have so far is applied _after_ the initial branch to the "reset" entry point. An upcoming change requires even this branch to be changed, so we apply the hook macro at the earliest point, and have the branch in the hook file as well. This is no functional change at this point, just refactoring to simplify upcoming patches.

* arm: imx: add HAB authentication of image to SPL bootSven Ebenfeld2017-01-02-0/+2
| | | | | | | | | | | | | | | | | | | | | When using HAB as secure boot mechanism on Wandboard, the chain of trust breaks immediately after the SPL. As this is not checking the authenticity of the loaded image before jumping to it. The HAB status output will not be implemented in SPL as it adds a lot of strings that are only required in debug cases. With those it exceeds the maximum size of the available OCRAM (69 KiB). The SPL MISC driver support must be enabled, so that the driver can use OTP fuse to check if HAB is enabled.

* ARM: revive CONFIG_USE_ARCH_MEMCPY/MEMSET for UniPhier and TegraMasahiro Yamada2016-12-27-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit be72591bcd64 ("Kconfig: Move USE_ARCH_MEMCPY/MEMSET to Kconfig") is misconversion. The original logic in include/configs/uniphier.h was as follows: #if !defined(CONFIG_SPL_BUILD) && !defined(CONFIG_ARM64) #define CONFIG_USE_ARCH_MEMSET #define CONFIG_USE_ARCH_MEMCPY #endif This means those configs were enabled when building U-Boot proper, but disabled when building SPL. Likewise for Tegra. Now "depends on !SPL" prevents any boards with SPL support from reaching these options. This changed the behavior for UniPhier and Tegra SoC family. Please notice these two options only control the U-Boot proper build. As you see arch/arm/Makefile, ARM-specific memset/memcpy are never compiled for SPL. So, __HAVE_ARCH_MEMCPY/MEMSET should not set for SPL.

* | mx6: ddr: pass mx6_ddr_sysinfo to calibration routinesEric Nelson2016-11-29-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DDR calibration routines have scattered support for bus widths other than 64-bits: -- The mmdc_do_write_level_calibration() routine assumes the presence of PHY1, and -- The mmdc_do_dqs_calibration() routine tries to determine whether one or two DDR PHYs are active by reading MDCTL. Since a caller of these routines must have a valid struct mx6_ddr_sysinfo for use in calling mx6_dram_cfg(), and the bus width is available in the "dsize" field, use this structure to inform the calibration routines which PHYs are active. This allows the use of the DDR calibration routines on CPU variants like i.MX6SL that only have a single MMDC port.

* | imx: mx6: ddr: add register MPZQLP2CTL for LPDDR2Eric Nelson2016-11-29-0/+2
| | | | | | | | | | | | | | | | | | Add constants for the MPZQLP2CTL DDR register for both banks to allow setting the LPDDR2 timing values in .cfg files using a named constant instead of hex addresses as is currently done in mx6slevk and other board files.

| | | | | | | | | | | | | | | | | | The ipu has two display interfaces. Make the used one a parameter in struct display_info_t instead of using unconditionally DI0. DI0 is the default setting. Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> Reviewed-by: Eric Nelson <eric@nelint.com>
