2022-05-02aspeed/smc: Add AST1030 supportSteven Lee1-0/+157
AST1030 spi controller's address decoding unit is 1MB that is identical to ast2600, but fmc address decoding unit is 512kb. Introduce seg_to_reg and reg_to_seg handlers for ast1030 fmc controller. In addition, add ast1030 fmc, spi1, and spi2 class init handler.

2021-10-12aspeed/smc: Add watchdog Control/Status RegistersCédric Le Goater1-1/+18
The Aspeed SoCs have a dual boot function for firmware fail-over recovery. The system auto-reboots from the second flash if the main flash does not boot successfully within a certain amount of time. This function is called alternate boot (ABR) in the FMC controllers. On AST2400/AST2500, ABR is enabled by hardware strapping in SCU70 to enable the 2nd watchdog timer, on AST2600, through register SCU510. If the boot on the the main flash succeeds, the firmware should disable the 2nd watchdog timer. If not, the BMC is reset and the CE0 and CE1 mappings are swapped to restart the BMC from the 2nd flash. On the AST2600, the ABR registers controlling the 2nd watchdog timer were moved from the watchdog register to the FMC controller and the FMC model should be able to control WDT2 through its own register set. This requires more work. For now, add dummy read/write handlers to let the FW disable the 2nd watchdog without error.

Current logic uses either s->burst_length or 32, whichever smaller, to determine how many bits it should read from the tx fifo each time. For example, for a 48 bit burst length, current logic transfers the first 32 bit from the first word in the tx fifo, followed by a 16 bit from the second word in the tx fifo, which is wrong. The correct logic should be: transfer the first 16 bit from the first word in the tx fifo, followed by a 32 bit from the second word in the tx fifo.

2021-02-02hw/ssi: imx_spi: Remove imx_spi_update_irq() in imx_spi_reset()Bin Meng1-4/+10
Usually the approach is that the device on the other end of the line is going to reset its state anyway, so there's no need to actively signal an irq line change during the reset hook. Move imx_spi_update_irq() out of imx_spi_reset(), to a new function imx_spi_soft_reset() that is called when the controller is disabled.

2020-12-10aspeed/smc: Add support for address lane disablementCédric Le Goater1-7/+18
The controller can be configured to disable or enable address and data byte lanes when issuing commands. This is useful in read command mode to send SPI NOR commands that don't have an address space, such as RDID. It's a good way to have a unified read operation for registers and flash contents accesses. A new SPI driver proposed by Aspeed makes use of this feature. Add support for address lanes to start with. We will do the same for the data lanes if they are controlled one day.
