2021-09-04gpio: Add a GPIO configSimon Glass
At present we have SPL_GPIO and TPL_GPIO but not piain GPIO. This works because there is a special build rule in Makefile that always includes the drivers/gpio directory. It is better to have all driver directories included by drivers/Makefile and there is already a rule in there for this purpose. It just needs a Kconfig for U-Boot proper, so add one. Enable the option always for now, since this mimics current behaviour. This can be updated once DM_GPIO is used everywhere. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-09-04dma: Add a Kconfig for legacy DMASimon Glass
We cannot use the existing DMA config for the MCD driver because it is not migrated to driver model. In order to move it to drivers/Makefile we need some sort of option for it. Add a new DMA_LEGACY option, which also acts as a signal that it should be migrated. Enable this for devkit3250 which uses CONFIG_DMA_LPC32XX which is not converted to Kconfig. For now this is not used in the Makefile. That update happens in a following patch. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-09-03xyz-modem: Allow to cancel transfer also by CTRL+CPali Rohár
Currently it is possible to cancel loadx and loady commands by pressing CTRL+X (CAN character) at least 3 times quickly. All other U-Boot commands, including loadb and loads can be cancelled by CTRL+C. So allow it also in xyz-modem code used by loadx and loady commands. Implement it by handling CTRL+C (ETX character) in the same way as CTRL+X (CAN character). Due to how x/y-modem protocol works, it is required to press CTRL+C or CTRL+X at least 3 times quickly.

2021-09-03xyz-modem: Fix crash after cancelling transferPali Rohár
Variable xyz.len is set to -1 on error. At the end xyzModem_stream_read() function calls memcpy() with length from variable xyz.len. If this variable is set to -1 then value passed to memcpy is casted to unsigned value, which means to copy whole address space. Which then cause U-Boot crash. E.g. on arm64 it cause CPU crash: "Synchronous Abort" handler, esr 0x96000006 Fix this issue by checking that value stored in xyz.len is valid prior trying to use it.

2021-09-02ARM: Prevent the compiler from using NEON registersSamuel Holland
For ARMv8-A, NEON is standard, so the compiler can use it even when no special target flags are provided. For example, it can use stores from NEON registers to zero-initialize large structures. GCC 11 decides to do this inside the DRAM init code for the Allwinner H6. However, GCC 11 has a bug where it generates misaligned NEON register stores even with -mstrict-align. Since the MMU is not enabled this early in SPL, the misaligned store causes an exception and breaks booting. Work around this issue by restricting the compiler to using GPRs only, not vector registers. This prevents any future surprises relating to NEON use as well.

2021-09-02arm: Use armv8_switch_to_el1 env to switch to EL1Peter Hoyes
Use the environment variable armv8_switch_to_el1 to determine whether to switch to EL1 at runtime. This is an alternative to the CONFIG_ARMV8_SWITCH_TO_EL1 compile-time option. The environment variable will be ineffective if the ARMV8_MULTIENTRY config is used. This is required by the Armv8r64 architecture, which must be able to boot at S-EL1 for Linux but may need to boot at other ELs for other systems. Signed-off-by: Peter Hoyes <Peter.Hoyes@arm.com>
2021-09-02vexpress64: Add BASER_FVP vexpress board variantPeter Hoyes
The BASER_FVP board variant is implemented on top of the BASE_FVP board config (which, in turn, is based on the Juno Versatile Express board config). They all share a similar memory map - for BASER_FVP the map is inverted from the BASE_FVP (https://developer.arm.com/documentation/100964/1114/Base-Platform/Base---memory/BaseR-Platform-memory-map) * Create new TARGET_VEXPRESS64_BASER_FVP target, which uses the same board config as BASE_FVP and JUNO * Adapt vexpress_aemv8a.h header file to support BASER_FVP (and rename to vexpress_aemv8.h) * Enable config to switch to EL1 for the BASER_FVP * Create vexpress_aemv8r defconfig * Provide an MPU memory map for the BASER_FVP For now, only single core boot is supported.

2021-09-02armv8: Add ARMv8 MPU configuration logicPeter Hoyes
Armv8r64 is the first Armv8 platform that only has a PMSA at the current exception level. The architecture supplement for Armv8r64 describes new fields in ID_AA64MMFR0_EL1 which can be used to detect whether a VMSA or PMSA is present. These fields are RES0 on Armv8a. Add logic to read these fields and, for the protection of the memory used by U-Boot, initialize the MPU instead of the MMU during init, then clear the MPU regions before transition to the next stage. Provide a default (blank) MPU memory map, which can be overridden by board configurations. Signed-off-by: Peter Hoyes <Peter.Hoyes@arm.com>
2021-09-02armv8: Ensure EL1&0 VMSA is enabledPeter Hoyes
On Armv8-R, the EL1&0 memory system architecture is configurable as a VMSA or PMSA, and resets to an "architecturally unknown" value. Add code to armv8_switch_to_el1_m which detects whether the MSA at EL1&0 is configurable using the id_aa64mmfr0_el1 register MSA fields. If it is we must ensure the VMSA is enabled so that a rich OS can boot. The MSA and MSA_FRAC fields are described in the Armv8-R architecture profile supplement (section G1.3.7): https://developer.arm.com/documentation/ddi0600/latest/ Signed-off-by: Peter Hoyes <Peter.Hoyes@arm.com>
2021-09-02armv8: Disable pointer authentication traps for EL1Peter Hoyes
The use of ARMv8.3 pointer authentication (PAuth) is governed by fields in HCR_EL2, which trigger a 'trap to EL2' if not enabled. The reset value of these fields is 'architecturally unknown' so we must ensure that the fields are enabled (to disable the traps) if we are entering the kernel at EL1. The APK field disables PAuth instruction traps and the API field disables PAuth register traps Add code to disable the traps in armv8_switch_to_el1_m. Prior to doing so, it checks fields in the ID_AA64ISAR1_EL1 register to ensure pointer authentication is supported by the hardware. The runtime checks require a second temporary register, so add this to the EL1 transition macro signature and update 2 call sites. Signed-off-by: Peter Hoyes <Peter.Hoyes@arm.com>

2021-09-02arm: mach-snapdrgon: misc: Simplify msm_generate_mac_addr()Stephan Gerhold
The logic in msm_generate_mac_addr() was originally taken from the LK bootloader where the serial number is a string and must be parsed first. However, in U-Boot msm_board_serial() returns an u32 and msm_generate_mac_addr() has quite complicated code that will first print it as a hex string and then immediately parse it again. What this function actually does at the end is to put the serial number encoded as big endian (the order used for the hex string) into the u8 *mac. Use put_unaligned_be32() to do that with bit shifts instead of going through the string format. This should be slightly more efficient and cleaner but does not result in any functional difference.

2021-09-02arm: mach-snapdragon: misc: Initialize eMMC if necessaryStephan Gerhold
At the moment U-Boot produces an empty MAC address (02:00:00:00:00:00) if the eMMC is not used by anything in U-Boot (e.g. with CONFIG_ENV_IS_NOWHERE=y instead of having the environment on eMMC). This happens because then there is nothing that actually initializes the eMMC and reads the "cid" that is later accessed. To fix this, call mmc_init() to ensure the eMMC is initialized. There is no functional difference if the eMMC is already initialized since then mmc_init() will just return without doing anything.

2021-09-02armv7: Add Position Independent Execution supportChia-Wei Wang
A U-Boot image could be loaded and executed at a different location than it was linked at. For example, Aspeed takes a stable release version of U-Boot image as the golden one for recovery purposes. When the primary storage such as flash is corrupted, the golden image would be loaded to any SRAM/DRAM address on demands through ethernet/UART/etc and run for rescue. To deal with this condition, the PIE is needed as there is only one signed, golden image, which could be however executed at different places. This patch adds the PIE support for ARMv7 platform.

2021-09-01rtc: ds1307: Fix incorrect clock reset for DS13xxCallum Sinclair
The ds1307 driver also supports the DS1339 and DS1340. However, in ds1307_rtc_reset the register writes assume that the chip is a DS1307. This is evident in the writing of bits SQWE, RS1, RS0 to the control register. While this applies correctly to the DS1307, on a DS1340 the control register doesn't contain those bits (instead, the register is used for clock calibration). By writing these bits the clock calibration will be changed and the chip can become non-functional after a reset call. Signed-off-by: Callum Sinclair <callum.sinclair@alliedtelesis.co.nz>
