Plus a few changes from Scott which came in a bit late. And then various fixes, mostly minor. Summary highlights: - rework the Linux page table geometry to lower memory usage on 64-bit Book3S (IBM chips) using the Hash MMU. - support for a new device tree binding for discovering CPU features on future firmwares. - Freescale updates from Scott: "Includes a fix for a powerpc/next mm regression on 64e, a fix for a kernel hang on 64e when using a debugger inside a relocated kernel, a qman fix, and misc qe improvements."

| * soc/fsl/qbman: Disable IRQs for deferred QBMan workRoy Pledge2017-04-301-0/+5
| | | | | | | | | | | | | | | | | | | | | | Work for Congestion State Notifications (CSCN) and Message Ring (MR) handling is handled via the workqueue mechanism. This requires the driver to disable those IRQs before scheduling the work and re-enabling it once the work is completed so that the interrupt doesn't continually fire.

| * soc/fsl/qe: only apply QE_General4 workaround on affected SoCsValentin Longchamp2017-04-301-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The QE_General4 workaround is only valid for the MPC832x and MPC836x SoCs. The other SoCs that embed a QUICC engine are not affected by this hardware bug and thus can use the computed divisors (this was successfully tested on the T1040). Similalry to what was done in commit 8ce795cb0c6b ("i2c: mpc: assign the correct prescaler from SVR") in order to avoid changes in the device tree nodes of the QE (with maybe a variant of the compatible property), the PVR reg is read out to find out if the workaround must be applied or not.

| * soc/fsl/qe: round brg_freq to 1kHz granularityValentin Longchamp2017-04-301-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because of integer computation rounding in u-boot (that sets the QE brg-frequency DTS prop), the clk value is 99999999 Hz even though it is 100 MHz. When setting brg clks that are exact divisors of 100 MHz, this small differnce plays a role and can result in lower clks to be output (for instance 20 MHz - divide by 5 - results in 16.666 MHz - divide by 6). This patch fixes that by "forcing" the brg_clk to the nearest kHz when the difference is below 2 integer rounding errors (i.e. 4).

* soc/fsl/qe: fix Oops on CPM1 (and likely CPM2)Christophe Leroy2016-09-251-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 0e6e01ff694ee ("CPM/QE: use genalloc to manage CPM/QE muram") has changed the way muram is managed. genalloc uses kmalloc(), hence requires the SLAB to be up and running. On powerpc 8xx, cpm_reset() is called early during startup. cpm_reset() then calls cpm_muram_init() before SLAB is available, hence the following Oops. cpm_reset() cannot be called during initcalls because the CPM is needed for console. This patch removes the call to cpm_muram_init() from cpm_reset(). cpm_muram_init() will be called from a new function called cpm_init() which is declared as subsys_initcall, unless cpm_muram_alloc() is called earlier for the serial console in which case cpm_muram_init() will be called from there. The reason for calling it from two places is that some drivers (e.g. i2c-cpm) need some of the initialisations done by cpm_muram_init() but don't call cpm_muram_alloc(). The console driver calls cpm_muram_alloc() but some platforms might not use the CPM serial ports for console.
