[U-Boot] [RFC PATCH 0/6] rockchip: rk3368: remove secure timer usage and use DM timer

[Philipp Tomsich]

Trying to answer Simon's question whether the address of the secure
timer (for initialising stimer1 and starting up the ARMv8 generic
timer) can be obtained from the DTS, here's a series that tries to
give an answer.

To summarise this answer in plain English:
- The answer to the original question is: "no, but..."
- The "but" is what's implemented here: we don't need the ARMv8
  generic timer ticking in U-Boot, so we won't have to initialise it
  at all (this removing the need to obtain the address for stimer1).
- We also have a "however": the size of the TPL binary increases by
  approx. 800 bytes, as we need the DM timer support.

This series is based on-top-of my RK3368 enablement series.

If we go ahead with merging this, then I'll have to add support for
the RK3399 as well...


Philipp Tomsich (6):
  timer: add OF_PLATDATA support for timer-uclass
  dm: timer: normalise SPL and TPL support
  rockchip: timer: add device-model timer driver for RK3368 (and
    similar)
  dts: rk3368: make timer0 accessible for SPL and TPL
  rockchip: lion-rk3368: defconfig: enable DM timer for all stages
  rockchip: rk3368: remove setup of secure timer from TPL/SPL
