Add Timer model for AST2700 Timer support. The Timer controller include 8 sets of 32-bit decrement counters. The base address of TIMER0 to TIMER7 as following. Base Address of Timer 0 = 0x12C1_0000 Base Address of Timer 1 = 0x12C1_0040 Base Address of Timer 2 = 0x12C1_0080 Base Address of Timer 3 = 0x12C1_00C0 Base Address of Timer 4 = 0x12C1_0100 Base Address of Timer 5 = 0x12C1_0140 Base Address of Timer 6 = 0x12C1_0180 Base Address of Timer 7 = 0x12C1_01C0 The interrupt of TIMER0 to TIMER7 as following. GICINT16 = TIMER 0 interrupt GICINT17 = TIMER 1 interrupt GICINT18 = TIMER 2 interrupt GICINT19 = TIMER 3 interrupt GICINT20 = TIMER 4 interrupt GICINT21 = TIMER 5 interrupt GICINT22 = TIMER 6 interrupt GICINT23 = TIMER 7 interrupt Signed-off-by: Jamin Lin <jamin_lin@aspeedtech.com> --- hw/arm/aspeed_ast27x0.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+)
