Subject: [PATCH v2 00/14] MXS low-level improvements
Date: Fri, 10 Aug 2018 18:34:46 +0200	[thread overview]
Message-ID: <20180810163500.12042-1-r.hieber@pengutronix.de> (raw)

While porting barebox onto a new old MX28 board, I had to extend the
low-level code to set up SDRAM and PMIC. Most of those changes are
probably also applicable to MX23 boards since the code paths are the
same, and are only wrapped in mx28_*/mx23_*-specific wrapper functions.

(Also, if anyone wants to port these changes back to U-Boot, feel free
to do so, it's the same code ☺)

Changes in v1 -> v2:
  - include cleaner memory size detection by Sascha, also for i.MX23
  - call mxs_mem_init_clock() explicitely from board code instead of
    passing the clock dividers through mx*_mem_init()
  - add parameter documentation for mxs_mem_init_clock()
  - Documentation: back-pedal on the statment that all boards are ported
    to barebox bootlets, there are still some i.MX23 boards that need
    Freescale bootlet code

Roland Hieber (11):
  images: MXS: allow generation of unencrypted bootstreams
  ARM: MXS: i.MX28: allow setup of low-voltage SDRAM
  ARM: MXS: allow configuration of EMI clock prescaler
  ARM: MXS: refactor mx2*_power_init source configuration
  ARM: MXS: allow starting from battery input without 4P2 source enabled
  ARM: MXS: make power levels configurable in mx2*_power_init
  ARM: MXS: fix VDDx brownout setup logic
  ARM: MXS: make VDDx brownout setup more understandable
  ARM: MXS: mxs_power_status: use less magic values
  ARM: MXS: mxs_power_status: align output
  Documentation: MXS: general update and improvements

Sascha Hauer (3):
  scripts: mxsimage: Allow unencrypted images
  ARM: i.MX28: Add memory size detection
  ARM: i.MX23: Add memory size detection
