Subject: [PATCH 0/3] firmware: add driver for lpc18xx boot ROM
Date: Tue, 13 Sep 2016 21:51:14 +0200 [thread overview]
Message-ID: <20160913195117.2887-1-manabian@gmail.com> (raw)
This patch set adds a firmware driver for the boot ROM found on all
NXP LPC18xx/43xx devices. The boot ROM contains serveral APIs that
is used to retrive device specific information and program the
internal Flash and OTP memories.
For now this driver only uses the API in the boot ROM to expose
device information via a 'SoC device'. Support for Flash and OTP
programming will be added later.
Also note that not all APIs are avaliable on all devices. The IAP
API that is used to retrive device information is only avaliable
on devices with Flash. Flashless devices retrive information from
OTP memory. To determin if IAP is avaliable one must check a
specific register in the CREG (syscon) block.
I intend to take this patch set via arm-soc/drivers through my
lpc18xx tree for 4.10.
