2020-06-17imx: mx7: fix DDRC size in A7-M4 mapping tableIgor Opaniuk
According to i.MX 7Solo Applications Processor Reference Manual, 2.1.3 Cortex-M4 Memory Map, M4 can address only 1536MB of DDRC (Start Address: 8000_0000; End Address: DFFF_FFFF). Correct DDRC size to 60000000. Relates-to: ELB-2806 Signed-off-by: Igor Opaniuk <igor.opaniuk@toradex.com>

Currently imx-specific bootaux command doesn't support ELF format firmware for Cortex-M4 core. This patches introduces a PoC implementation of handling elf firmware (load_elf_image_phdr() was copy-pasted from elf.c just for PoC). This has the advantage that the user does not need to know to which address the binary has been linked to. However, in order to handle and load the elf sections to the right address, we need to translate the Cortex-M4 core memory addresses to primary/host CPU memory addresses (Cortex A7/A9 cores). This allows to boot firmwares from any location with just using bootaux, e.g.: > tftp ${loadaddr} hello_world.elf && bootaux ${loadaddr} Similar translation table can be found in the Linux remoteproc driver [1].

2019-12-23board: colibri_imx7: reserve DDR memory for Cortex-M4Igor Opaniuk
i.MX 7's Cortex-M4 core can run from DDR and uses DDR memory for the rpmsg communication. Both use cases need a fixed location of memory reserved. For the rpmsg use case the reserved area needs to be in sync with the kernel's hardcoded vring descriptor location. Use the linux,usable-memory property to carve out 1MB of memory in case the M4 core is running. Also make sure that the i.MX 7 specific rpmsg driver does not get loaded in case we do not carve out memory.

2019-07-05mips: mt76xx: Implement new d-cache fix in last_stage_init()Stefan Roese
With commit 06985289d452 ("watchdog: Implement generic watchdog_reset() version") the init sequence has changed in arch_misc_init(), resulting in a re-appearance of the d-cache issue on MT7688 boards (e.g. gardena). When this happens, the first (or sometimes later ones as well) TFTP command hangs and does not complete correctly. This leads to the assumption that the d-cache is not in a clean state once the ethernet driver is called (d-cache is used here for the buffers). The old work- around with the cache flush somehow does not work any more now with the new code change. Unfortunately adding CONFIG_SYS_MALLOC_CLEAR_ON_INIT also did not fix this issue. With v2019.07-rc3 it shows again. The time of accessing the data seems to be very important here. It needs to be "very late" in the boot process. Testing has shown, that copying a 64KiB area in DDR at a very late bootup time, directly before calling into the prompt, fixes this issue. Flushing of the complete d-cache does not seem to necessary, as this copy alone seems to fix this problem.

This uclass is intended for devices that do not need any features from the uclass, including binding children. This will typically be used by devices that are used to bind child devices but do not use dm_scan_fdt_dev() to do it. That is for example the case of several USB wrappers that have 2 child devices (1 for device and 1 for host) but bind only one at a any given time.
