For the AST2600 A3, SCU004 is set to 0x05030303 and SCU014 is set to 0x05030303. In the "aspeed_ast2600_scu_reset" function, the hardcoded value "AST2600_A3_SILICON_REV" is set in SCU004, and "s->silicon_rev" is set in SCU014. The value of "s->silicon_rev" is set by the SOC layer via the "silicon-rev" property. However, the design of the AST2700 is different. There are two SCU controllers: SCU0 (CPU Die) and SCU1 (IO Die). In the AST2700, the firmware reads the SCU Silicon Revision ID register (SCU0_000) and the SCUIO Silicon Revision ID register (SCU1_000), combining them into a single 64-bit value. The upper 32 bits represent the SCUIO, while the lower 32 bits correspond to the SCU. For example, the AST2700-A1 revision is represented as 0x0601010306010103. SCUIO_000 occupies bits [63:32] with a value of 0x06010103 and SCU_000 occupies bits [31:0] with a value of 0x06010103.

However, if users want to install FMC flash contents as a boot ROM, the DRAM address 0x400000000 would be overwritten with Boot ROM data. This causes the AST2700 to fail to boot because the U-Boot data becomes incorrect. To fix this, change the ASPEED_DEV_SPI_BOOT address to "0x100000000", which is the FMC0 memory-mapped start address in the AST2700.

Previously, the formula "address & 0x0f00" was used to derive the IRQ index numbers. However, the INTC controller also supports GICINT192_201, mapping 1 input IRQ pin to 10 output IRQ pins. The pin numbers for input and output are different. It is difficult to use a formula to determine the index number of INTC model supported input and output IRQs. To simplify and improve readability, introduces the AspeedINTCIRQ structure to save the input/output IRQ index and its enable/status register address. Introduce the "aspeed_2700_intc_irqs" table to store IRQ information for INTC. Introduce the "aspeed_intc_get_irq" function to retrieve the input/output IRQ pin index from the provided status/enable register address.

} -- 2.48.1 From: Jamin Lin <jamin_lin@aspeedtech.com> The design of INTC controllers has significantly changed in AST2700 A1. There are a total of 480 interrupt sources in AST2700 A1. For interrupt numbers from 0 to 127, they can route directly to PSP, SSP, and TSP. Due to the limitation of interrupt numbers of processors, the interrupts are merged every 32 sources for interrupt numbers greater than 127. There are two levels of interrupt controllers, INTC(CPUD Die) and INTCIO (IO Die). The interrupt sources of INTC are the interrupt numbers from INTC_0 to INTC_127 and interrupts from INTCIO. The interrupt sources of INTCIO are the interrupt numbers greater than INTC_127. INTC_IO controls the interrupts INTC_128 to INTC_319 only. Currently, only GIC 192 to 201 are supported, and their source interrupts are from INTCIO and connected to INTC at input pin 0 and output pins 0 to 9 for GIC 192-201. The design of the orgates for GICINT 196 is as follows: It has interrupt sources ranging from 0 to 31, with its output pin connected to INTCIO "T0 GICINT_196". The output pin is then connected to INTC "GIC_192_201" at bit 4, and its bit 4 output should be connected to GIC 196. The design of INTC GIC_192_201 have 10 output pins, mapped as following: Bit 0 -> GIC 192 Bit 1 -> GIC 193 Bit 2 -> GIC 194 Bit 3 -> GIC 195 Bit 4 -> GIC 196 To support both AST2700 A1 and A0, INTC input pins 1 to 9 and output pins 10 to 18 remain to support GIC 128-136, which source interrupts from INTC. These will be removed if we decide not to support AST2700 A0 in the future. |-------------------------------------------------------------------------------------------------------| | AST2700 A1

VGA0 SCRATCH register to indicate that DDR training has completed, thus skipping the dram_init(). To align with the recent U-Boot changes, where the Main Control Register's BIT16 is checked to skip the dram_init() process, this patch sets BIT16 in the SDMC Main Control Register at reset time. This allows both the main U-Boot stage to correctly detect and bypass DRAM initialization when running under QEMU.

BIT[6] (SCU_FREQ_DONE) indicates the measurement is finished. Firmware polls BIT[6] to determine when measurement is complete. The flag can be cleared by writing BIT[1] to 0. To simulate this hardware behavior in QEMU: If BIT[1] is set to 1, BIT[6] is immediately set to 1 to avoid firmware hanging during polling. If BIT[1] is cleared to 0, BIT[6] is also cleared to 0 to match hardware semantics. The initial value of this register is initialized to 0x80, reflecting the default value confirmed from an EVB register dump.
