These areas are protected by the memory controller and will result in an external abort if accessed like common read/write memory. On the legacy boot loaders, these were set aside by using cmdline arguments such as this: mem=96M@0 mem_mtrace=15M@96M mem_mshared=1M@111M mem_modem=16M@112M mali.mali_mem=32M@128M mem=96M@160M hwmem=127M@256M mem_issw=1M@383M mem_ram_console=1M@384M mem=638M@385M Reserve the relevant areas in the device tree instead. The "mali", "hwmem", "mem_ram_console" and the trailing 1MB at the end of the memory reservations in the list are not relevant for the upstream kernel as these are nowadays replaced with upstream technologies such as CMA. The modem and ISSW reservations are necessary. This was manifested in a bug that surfaced in response to commit 7fef431be9c9 ("mm/page_alloc: place pages to tail in __free_pages_core()") which changes the behaviour of memory allocations in such a way that the platform will sooner run into these dangerous areas, with "Unhandled fault: imprecise external abort (0xc06) at 0xb6fd83dc" or similar: the real reason turns out to be that the PTE is pointing right into one of the reserved memory areas. We were just lucky until now. We need to augment the DB8500 and DB8520 SoCs similarly and also create a new include for the DB9500 used in the Snowball since this does not have a modem and thus does not need the modem memory reservation, albeit it needs the ISSW reservation.

If there is no phy-handle specified, the FEC driver will scan the PHY bus for a PHY and use that. Consequently, adding the DT configuration of the PHY and the phy properties to the FEC driver broke some boards.
