ARM: shmobile: r8a7790: Instantiate GIC from C board code in legacy builds
As of commit 9a1091ef ("irqchip: gic: Support hierarchy irq domain."), the Lager legacy board support is known to be broken. The IRQ numbers of the GIC are now virtual, and no longer match the hardcoded hardware IRQ numbers in the legacy platform board code. To fix this issue specific to non-multiplatform r8a7790 and Lager: 1) Instantiate the GIC from platform board code and also 2) Skip over the DT arch timer as well as 3) Force delay setup based on DT CPU frequency With these 3 fixes in place interrupts on Lager are now unbroken. Partially based on legacy GIC fix by Geert Uytterhoeven, thanks to him for the initial work. Signed-off-by:Magnus Damm <damm+renesas@opensource.se> Acked-by:
