* spl: Introduce SPL_DM_GPIO Kconfig defineWIP/2019-10-11-master-importsLukasz Majewski2019-10-111-0/+6
| | | | | | | | This define indicates if DM_GPIO shall be supported in SPL. This allows proper operation of DM converted GPIO drivers in SPL, which use boards. Signed-off-by: Lukasz Majewski <lukma@denx.de>

* sandbox: Remove sandbox_noblk buildTom Rini2019-10-113-191/+1
| | | | | | | | | | | | | | At this point, all drivers that do not use CONFIG_BLK are past their migration deadlines, so remove this config as it's no longer helpful and hinders enhancing block drivers. Cc: Simon Glass <sjg@chromium.org> Cc: Faiz Abbas <faiz_abbas@ti.com> Signed-off-by: Tom Rini <trini@konsulko.com> --- This is required for Faiz's series that adds UFS support to SCSI as that breaks the non-BLK case. This path seems the most reasonable at this point in time.
* spl: Introduce SPL_DM_SPI Kconfig defineLukasz Majewski2019-10-111-0/+7
| | | | | | | | | This define indicates if DM_SPI shall be supported in SPL. This allows proper operation of DM converted SPI drivers in SPL, which use #if !CONFIG_IS_ENABLED(DM_SPI) to also support not yet DM/DTS converted boards. Signed-off-by: Lukasz Majewski <lukma@denx.de>
* arm64: print instructions leading to exceptionHeinrich Schuchardt2019-10-111-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an exception occurs in a loaded image and the relocation offset is unknown, it is helpful to know the instructions pointed to by the program counter. This patch adds the missing output. A possible output is: Code: 910c4021 aa1303e0 f9400662 d63f0040 (e7f7defb) The parentheses indicate the instruction causing the exception. The output can be disassembled using scripts/decodecode: echo 'Code: 90000360 9100b800 94002782 17ffff8f (e7f7defb)' | \ ARCH=arm64 scripts/decodecode Code: 90000360 9100b800 94002782 17ffff8f (e7f7defb) All code ======== 0: 90000360 adrp x0, 0x6c000 4: 9100b800 add x0, x0, #0x2e 8: 94002782 bl 0x9e10 c: 17ffff8f b 0xfffffffffffffe48 10:* e7f7defb .inst 0xe7f7defb ; undefined <-- trapping instruction Code starting with the faulting instruction =========================================== 0: e7f7defb .inst 0xe7f7defb ; undefined We already have implemented the same for armv7.

* ARM: asm/io.h: kill off confusing #ifdef __mem_pci blockRasmus Villemoes2019-10-111-41/+0
| | | | | | | | | | | | | No ARM board seems to define __mem_pci - and if it did, one would get tons of ./arch/arm/include/asm/io.h:307:0: warning: "readl" redefined warnings, because readl and friends are unconditionally defined earlier in io.h. Moreover, the redefinitions lack the memory barriers that the first definitions have. So I'm guessing this is practically dead code. Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

It is necessary in the case when one wants to boot (through falcon boot) from eMMC after loading SPL from other memory (like SPI-NOR).

* spi: bcm63xx_hsspi: Continue init when using no reset and fixed-clock.Kursad Oney2019-10-111-10/+9
| | | | | | | | | | | | | | | The Broadcom ARM implementations do not yet have a clock framework so one can use a fixed clock as the root clock of the hsspi block. The fixed clock does not have an "enable" routine, since it's always enabled. So when we hit this issue, getting an ENOSYS return, do not bail but continue initialization. Similarly the block might already have been out of reset, say, when we are booting from a SPI device. So if the reset signal is not configured in the device tree, do not bail out and instead skip deasserting the reset.
