ppc440_sdram: QOM'ify

2022-10-17T19:15:09+00:00

Change the ppc440_sdram model to a QOM class derived from the PPC4xx-dcr-device and name it ppc4xx-sdram-ddr2. This is mostly modelling the DDR2 SDRAM controller found in the 460EX (used on the sam460ex board). Newer SoCs (regardless of their PPC core, e.g. 405EX) may have this controller but we only emulate enough of it for the sam460ex u-boot firmware.

ppc440_sdram: Move RAM size check to ppc440_sdram_init

2022-10-17T19:15:09+00:00

Move the check for valid memory sizes from board to sdram controller init. This adds the missing valid memory sizes of 16 and 8 MiB to the DoC and the board now only checks for additional restrictions imposed by its firmware then sdram init checks for valid sizes for SoC.

ppc440_sdram: Get rid of the init RAM hack

2022-10-17T19:15:09+00:00

Remove the do_init parameter of ppc440_sdram_init and enable SDRAM controller from the board. Firmware does this so it may only be needed when booting with -kernel without firmware but we enable SDRAM unconditionally to preserve previous behaviour.

ppc4xx: Use Ppc4xxSdramBank in ppc4xx_sdram_banks()

2022-10-17T19:15:09+00:00

Change ppc4xx_sdram_banks() to take one Ppc4xxSdramBank array instead of the separate arrays and adjust ppc4xx_sdram_init() and ppc440_sdram_init() accordingly as well as machines using these.

ppc440_uc: Basic emulation of PPC440 DMA controller

2018-07-02T23:56:52+00:00

PPC440 SoCs such as the AMCC 460EX have a DMA controller which is used by AmigaOS on the sam460ex. Implement the parts used by AmigaOS so it can get further booting on the sam460ex machine. Signed-off-by: BALATON Zoltan Signed-off-by: David Gibson

ppc4xx: Add device models found in PPC440 core SoCs

These devices are found in newer SoCs based on 440 core e.g. the 460EX (http://www.embeddeddeveloper.com/assets/processors/amcc/datasheets/ PP460EX_DS2063.pdf) Signed-off-by: BALATON Zoltan Signed-off-by: David Gibson
