Commit b81406db ("arm: serial: Add debug UART capability to the pl01x driver") add supports to use pl01x as a debug UART. However, due to CONFIG_IS_ENABLED macro requires CONFIG_SPL_* prefix, the _debug_uart_init() would not choose TYPE_PL011 in SPL build. This patch fixes the bug by judging CONFIG_DEBUG_UART_PL011 explicitly. Signed-off-by: NChen Baozi <chenbaozi@phytium.com.cn> Reviewed-by: NSimon Glass <sjg@chromium.org>

CNTFRQ_EL0 is only writable from the highest supported exception level on the platform. For Armv8-A, this is typically EL3, but technically EL2 and EL3 are optional so it may need to be initialized at EL2 or EL1. For Armv8-R, the highest exception level is always EL2. This patch moves the initialization outside of the switch_el block and uses a new macro branch_if_not_highest_el which dynamically detects whether it is at the highest supported exception level. Linux's docs state that CNTFRQ_EL0 should be initialized by the bootloader. If not set, the the U-Boot prompt countdown hangs. Signed-off-by: NPeter Hoyes <Peter.Hoyes@arm.com>

For some reason, the DragonBoard 410c aborts autoboot immediately if U-Boot is started without LK. It looks like it picks up a single broken character via serial and therefore believes a key was pressed to abort autoboot. After some debugging, it seems like adding some delay after pinctrl setup but before UART initialization fixes the issue. It's also worth mentioning that unlike when booting from LK, the pinctrl setup is actually necessary when booting U-Boot without LK since UART is broken if the pinctrl line is removed. I suspect that reconfiguring the pins might take some time to stabilize and if the UART controller is enabled too quickly it will pick up some random noise. Adding a few milliseconds of delay fixes the issue and shouldn't have any other negative side effects. 3ms seems to be the minimum delay required in my tests, use 5ms instead just to be sure.

At the moment pressing the volume down key does not actually launch fastboot. This is because setting "bootdelay" to "-1" actually disables autoboot and drops to the U-Boot console. It does not execute the "bootcmd". The correct value for "bootdelay" here would be "-2", which disables the delay and key checking and would immediately execute the "bootcmd". However, even better in this case is using "preboot" to trigger Fastboot. The advantage is that running "fastboot continue" will actually continue the autoboot process instead of ending up in the U-Boot shell. Also make sure to unset "preboot" again immediately in case the user saves the environment after triggering fastboot.

The DragonBoard 410c has proprietary firmware from Qualcomm that reserves 8 MiB of memory for tz/smem/hyp/rmtfs/rfsa from 0x86000000 to 0x86800000. I'm not aware of any ATF (ARM Trusted Firmware) port for DB410c that would reserve 30 MiB of memory at the end of RAM. I suspect the comment might have been copied from hikey.h which has a very similar comment (and which actually does have an ATF port). Reducing the memory size just prevents U-Boot from using the end of the RAM, not the reserved region inbetween. Therefore we might as well display the correct DRAM size (1 GiB) instead of strange 986 MiB.

At the moment the U-Boot port for the DragonBoard 410c is designed to be loaded as an Android boot image after Qualcomm's Little Kernel (LK) bootloader. This is simple to set up but LK is redundant in this case, since everything done by LK can be also done directly by U-Boot. Dropping LK entirely has at least the following advantages: - Easier installation/board code (no need for Android boot images) - (Slightly) faster boot - Boot directly in 64-bit without a round trip to 32-bit for LK So far this was not possible yet because of unsolved problems: 1. Signing tool: The firmware expects a "signed" ELF image with extra (Qualcomm-specific) ELF headers, usually used for secure boot. The DragonBoard 410c does not have secure boot by default but the extra ELF headers are still required. 2. PSCI bug: There seems to be a bug in the PSCI implementation (part of the TrustZone/tz firmware) that causes all other CPU cores to be started in 32-bit mode if LK is missing in the boot chain. This causes Linux to hang early during boot. There is a solution for both problems now: 1. qtestsign (https://github.com/msm8916-mainline/qtestsign) can be used as a "signing" tool for U-Boot and other firmware. 2. A workaround for the "PSCI bug" is to execute the TZ syscall when entering U-Boot. That way PSCI is made aware of the 64-bit switch and starts all other CPU cores in 64-bit mode as well. Simplify the dragonboard410c board by removing all the extra code that is only used to build an Android boot image that can be loaded by LK. This allows dropping the custom linker script, special image magic, as well as most of the special build/installation instructions. CONFIG_REMAKE_ELF is used to build a new ELF image that has both U-Boot and the appended DTB combined. The resulting u-boot.elf can then be passed to the "signing" tool (e.g. qtestsign). The PSCI workaround is placed in the "boot0" hook that is enabled with CONFIG_ENABLE_ARM_SOC_BOOT0_HOOK. The extra check for EL1 allows compatibility with custom firmware that enters U-Boot in EL2 or EL3, e.g. qhypstub (https://github.com/msm8916-mainline/qhypstub). As a first step these changes apply only to DragonBoard410c. Similar changes could likely also work for the DragonBoard 820c. Note that removing LK wouldn't be possible that easily without a lot of work already done three years ago by Ramon Fried. A lot of missing initialization, pinctrl etc was already added back then even though it was not strictly needed yet.

The ARM Juno boards can be used as somewhat decent machines to run off-the-shelf distributions, with USB, SATA, GBit Ethernet and 8GB of DRAM. With stable DTs in the board's NOR flash this would work really nicely, however the default boot command is to fetch a kernel and an initrd from the on-board NOR flash, which sounds somewhat embedded. Include the config_distro_bootcmd.h header and define the available devices (starting with USB, to catch USB installer sticks) to make distributions and UEFI work out of the box. The NOR flash kernel functionality is still preserved as the last resort, should all other methods fail.

The generic distro boot sequence iterates over several types of devices, trying one after another. In doing do, it starts with setting the "devtype" variable, then uses this later in more generic commands. Now most (block) device types use a local variable for that, but DHCP puts the type into the environment, where it shadows any local variables. As a consequence any boot attempt after bootcmd_dhcp has been run fails: =========================== VExpress64# run bootcmd_dhcp ... VExpress64# run bootcmd_sata0 SATA#0: (3.0 Gbps) SATA#1: (No RDY) Device 0: Model: 16GB SATA Flash Drive .... ... is now current device Couldn't find partition dhcp 0:1 =========================== This problem typically doesn't show, because DHCP is mostly the last command to try, but is a problem when this order is different, or when distro_bootcmd or bootcmd_xxx are run separately or multiple times. Let bootcmd_dhcp use a local variable, as the other kids do, to make the order of boot commands irrelevant, and allow repeated calls.
