Subject: [PATCH 1/4] mips: bmips: rework and cache CBR addr handling
Rework the handling of the CBR address and cache it. This address
doesn't change and can be cached instead of reading the register every
time.
This is in preparation of permitting to tweak the CBR address in DT with
broken SoC or bootloader.
bmips_cbr_addr is defined in setup.c for each arch to keep compatibility
with legacy brcm47xx/brcm63xx and generic BMIPS target.

From b95b30e50aed225d26e20737873ae2404941901c Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/4] mips: bmips: setup: make CBR address configurable
Add support to provide CBR address from DT to handle broken
SoC/Bootloader that doesn't correctly init it. This permits to use the
RAC flush even in these condition.
To provide a CBR address from DT, the property "brcm,bmips-cbr-reg"
needs to be set in the "cpus" node. On DT init, this property presence
will be checked and will set the bmips_cbr_addr value accordingly. Also
bmips_rac_flush_disable will be set to false as RAC flush can be
correctly supported.
The CBR address from DT will overwrite the cached one and the
one set in the CBR register will be ignored.
Also the DT CBR address is validated on being outside DRAM window.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The data RAC is left disabled by the bootloader in some SoCs, at least in
the core it boots from.
Enabling this feature increases the performance up to +30% depending on the
task.

+
+Required properties:
+
+- compatible: Should be "brcm,bcm6345-ext-intc" or "brcm,bcm6318-ext-intc".
+- reg: Specifies the base physical addresses and size of the registers.
+- interrupt-controller: identifies the node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an interrupt
+ source, Should be 2.
+- interrupt-parent: Specifies the phandle to the parent interrupt controller
+ this one is cascaded from.
+- interrupts: Specifies the interrupt line(s) in the interrupt-parent controller
+ node, valid values depend on the type of parent interrupt controller.
+
+Optional properties:
+
+- brcm,field-width: Size of each field (mask, clear, sense, ...) in bits in the

This reverts commit 03a539c7a118427a6609a26461358c56ac8f3a06.
Macronix block protection doesn't seem to be supported on Sercomm H-500s
devices since it hangs the device.
