Initialise rpi-firmware before clk-bcm2835
The IMA (Integrity Measurement Architecture) looks for a TPM (Trusted
Platform Module) having been registered when it initialises; otherwise
it assumes there is no TPM. It has been observed on BCM2835 that IMA
is initialised before TPM, and that initialising the BCM2835 clock
driver before the firmware driver has the effect of reversing this
order.
Change the firmware driver to initialise at core_initcall, delaying the
BCM2835 clock driver to postcore_initcall.

dwc_otg: fiq_fsm: add a barrier on entry into FIQ handler(s)
On BCM2835, there is no hardware guarantee that multiple outstanding
reads to different peripherals will complete in-order. The FIQ code
uses peripheral reads without barriers for performance, so in the case
where a read to a slow peripheral was issued immediately prior to FIQ
entry, the first peripheral read that the FIQ did could end up with
wrong read data returned.
Add dsb(sy) on entry so that all outstanding reads are retired.
The FIQ only issues reads to the dwc_otg core, so per-read barriers
in the handler itself are not required.
On BCM2836 and BCM2837 the barrier is not strictly required due to
differences in how the peripheral bus is implemented, but having
arch-specific handlers that introduce different latencies is risky.

The hcd would unconditionally set the transfer length to the endpoint

was less than the length of returned data, random memory would get
scribbled over, with bad effects if it crossed a page boundary.
Force a babble error if this happens by limiting the max transfer size

Revert "brcmfmac: Disable power management"
Shortly after the release of the Pi 3B, a loss of SSH connectivity
over WiFi was traced to the power management handling, so power
management was disabled. And so it has remained ever since.
Enabling power management saves 55mA (~270mW) on a Pi 4B, so is very
much worth the minimal effort of reverting this patch, which was
squashed and rebased many times since then to the commit hash is
meaningless.

MMU exception conditions are reported in the V3D_MMU_CTRL register as
write-1-to-clear (W1C) bits. The MMU interrupt handling code clears any
exceptions, but does so by masking out any other bits and writing the
result back. There are some important control bits in that register,
including MMU_ENABLE, so a safer approach is to simply write back the
value just read unaltered.

does reduce the impact to just an error in the kernel log.
