2015-02-24ARM: shmobile: kzm9g-reference: Remove board C code and DT fileSimon Horman1-62/+0
Now that the sh73a0 generic multiplatform case has the same feature set as the kzm9g DT reference board code, we get rid of the latter. DT reference code in the future shall make use of the sh73a0 multiplatform support code with the generic SoC machine vector.

2014-08-20ARM: shmobile: kzm9g-reference: Remove unneeded nr_irqs initializationGeert Uytterhoeven1-1/+0
As per arch_probe_nr_irqs(), the default value is NR_IRQS, which maps to NR_IRQS_LEGACY if CONFIG_SPARSE_IRQ=y. Since SPARSE_IRQ is selected by both ARCH_MULTIPLATFORM and ARCH_SHMOBILE_LEGACY, it's always enabled on shmobile.

2014-05-30ARM: l2c: shmobile: remove cache size overrideRussell King1-1/+1
The cache size should already be present in the L2 cache auxiliary control register: it is part of the integration process to configure the hardware IP. Most platforms get this right, yet still many cargo-cult program, and assume that they always need specifying to the L2 cache code. Remove them so we can find out which really need this.

2014-05-30ARM: l2c: remove platforms/SoCs setting early BRESPRussell King1-2/+2
Since we now automatically enable early BRESP in core L2C-310 code when we detect a Cortex-A9, we don't need platforms/SoCs to set this bit explicitly. Instead, they should seek to preserve the value of bit 30 in the auxiliary control register.

2013-03-18ARM: shmobile: kzm9g: Reference DT implementationSimon Horman1-0/+87
Provide alternate board code for the kzm9g to demonstrate how DT may be used given the current state of driver device tree support. This is intended to act as a reference for mach-shmobile developers. Some notes: * Brings up the GIC interrupt handler using device tree * Brings up the following device using device tree: - MMCIF (MMC) * Does not bring up the INTC interrupt controller at all, thus external devices may not be used. In particular, the SMSC ethernet device may not be used and thus NFS root may not be used. * Uses existing C code and not device tree to initialise the following, which are needed for a working board: - SCIF (Serial) - CMT (Clock) - PFC (GPIO) To use this alternate board code instead of the normal board code, CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config. And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used. Includes fix by Thierry Reding to no longer use gic_handle_irq() Includes fixes by Guennadi Liakhovetski for recent pinmux changes.
