Cover letter [PATCH 0/2] Add support for PL172 memory-controller

Hi Joachim,

Quoted 10 lines · Joachim Eastwood

This patch set adds support for setting up static memory devices on a ARM PrimeCell MultiPort Memory Controller (PL172) from DT. Dynamic memory (SDRAM) is not supported in this patch set.

DT bindings for PL172 is based on the bindings for the TI AEMIF memory controller. PL172 can be found on a number of NXP devices like the LPC18xx family.

Tested on Embedded Artists' LPC4357 Developer's Kit with NOR Flash (SST39VF320) and 74LCV16374 (gpio-74x164) on MPMC.

Please excuse my ignorance here, but is this memory controller used to manage the memory in use by the kernel? If so, how is it safe to reconfigure it dynamically at runtime? If not, then it might be worth describing some typical use-cases in the binding documentation to motivate the existence of this driver.

Cheers,

Will
