Lephe	2cdf925f94	interrupts: save caller-saved registers in main handler ... This is an obvious requirement for the interrupt routine, which was forgotten and only surfaced when I used a timer callback started with multiplications in an innocent add-in. r0..r7 are saved automatically, which leaves pr, gbr, mach et macl susceptible to corruption by the interrupt handler.	2020-05-06 20:45:35 +02:00
lephe	04231ea5d6	dma: add a new driver to support r61524 ... Also add a power interface (without driving code) and switch toolchain because the previous sh4eb-nofpu-elf toolchain was not completely FPU-free.	2019-03-10 15:45:34 +01:00
