2020-03-24ARM: dts: stm32mp1: DT alignment with Linux 5.6-rc1Patrick Delaunay
This commit manages diversity for STM32M15x SOCs with: - dedicated files to support all STM32MP15 SOCs family. The differences between those SOCs are: -STM32MP151 [1]: common file. -STM32MP153 [2]: STM32MP151 + CANs + a second CortexA7-CPU. -STM32MP157 [3]: STM32MP153 + DSI + GPU. - new files to manage security diversity on STM32MP15x SOCs. On STM32MP15xY, "Y" gives information: -Y = A means no cryp IP and no secure boot. -Y = C means cryp IP + secure boot. - stm32mp157 pinctrl files to better manage package diversity.

This is U-Boot own code, and no longer used since commit 36dd5f1b8abc ("dtc: Switch to building and using our own dtc unless provided"). Prior to that commit, U-Boot relied on an external dtc, so this script was used to check the dtc version. Now U-Boot bundles our own dtc in script/dtc/dtc like Linux kernel. Users are still allowed to pass DTC= option from the command line, but they are supposed to choose correct version of dtc in this case. So, we do not check the dtc version any more.

2020-03-16fixdep: fix U-Boot own code to handle only valid symbol charactersMasahiro Yamada
Currently, fixdep skips parsing include/linux/kconfig.h, but if it parsed it, it would translate the following code in kconfig.h config_enabled(CONFIG_VAL(option##_MODULE) into: $(wildcard include/config/option##/module.h) When Kbuild includes .*.cmd, it would emit the following error: *** unterminated call to function 'wildcard': missing ')'. Stop. This issue prevents us from importing the upstream Linux commit 638e69cf2230 ("fixdep: do not ignore kconfig.h"). Fix this by handling only alphanumerical characters and underscores. This makes sense because they match to the valid character sets in Kconfig symbols. As a side-note, you can reproduce this issue only on GNU Make <= 4.2.1 For GNU Make <= 4.2.1, the '#' always means the start of a comment. Hence, GNU Make thinks the closing ')' is missing. The following commit in GNU Make changed how it handles '#' in function invocations.

2020-03-16remoteproc: k3-r5: Fix rproc init failure on Split-mode _only_ devicesSuman Anna
The R5F subsystem/cluster on K3 SoCs can support both LockStep and Split-modes (superset) or just Split-mode depending on an eFUSE capability register. The LockStep configuration bit is Read-only though on Split-mode _only_ devices and as such the System Firmware does not allow the LockStep mode bit to be configured on such devices. The current logic in k3_r5f_rproc_configure() fails on Split-mode devices because of this unconditional programming of the LockStep mode bit, and results in the probe failure shown during the "rproc init" step at U-Boot prompt. Fix this by limiting the LockStep mode bit clear configuration only on devices supporting both LockStep/Split-modes.

2020-03-16remoteproc: k3-r5: Fix rproc init failure for Main R5FSS0Suman Anna
The Main R5FSS0 cluster is also enabled to probe the R5F remoteproc driver within R5 SPL for booting the Core0 very early. This results in a ti_sci_power_domain_on failure during the probe from the A72 U-Boot when "rproc init" is executed at U-Boot prompt, and doesn't enumerate all the rproc devices. Fix this by suppressing the power_domain_on altogether using the flag DM_FLAG_DEFAULT_PD_CTRL_OFF added in commit af94ad418dc7 ("dm: core: Allow for not controlling the power-domain by DM framework").

2020-03-16remoteproc: k3-dsp: Add support for L2RAM loading on C66x DSPsSuman Anna
The resets for the DSP processors on K3 SoCs are managed through the Power and Sleep Controller (PSC) module. Each DSP typically has two resets - a global module reset for powering on the device, and a local reset that affects only the CPU while allowing access to the other sub-modules within the DSP processor sub-systems. The C66x DSPs have two levels of internal RAMs that can be used to boot from, and the firmware loading into these RAMs require the local reset to be asserted with the device powered on/enabled using the module reset. Enhance the K3 DSP remoteproc driver to add support for loading into the internal RAMs. The local reset is deasserted on SoC power-on-reset, so logic has to be added in probe in remoteproc mode to balance the remoteproc state-machine. Note that the local resets are a no-op on C71x cores, and the hardware does not supporting loading into its internal RAMs. Signed-off-by: Suman Anna <s-anna@ti.com>
2020-03-16armv8: K3: j721e: Add DSP internal memory regions in MMU tableSuman Anna
The A72 U-Boot code supports early load and boot of a number of remote processors including the C66_0 and C66_1 DSPs. The current code supports only loading into the DDR regions which were already given the appropriate memory attributes. The C66 DSPs also have L1 and L2 internal memory regions that can behave as normal-memories. Add a new entry to the J721E MMU table covering these regions with the appropriate memory attributes to allow the A72 U-Boot code to support loading directly into these memory regions.
