ppc4xx_sdram: Move ppc4xx_sdram_banks() to ppc4xx_sdram.c

2022-10-28T16:15:23+00:00

This function is only used by the ppc4xx memory controller models so it can be made static. Signed-off-by: BALATON Zoltan Reviewed-by: Daniel Henrique Barboza Message-Id: Signed-off-by: Daniel Henrique Barboza

ppc440_uc.c: Move some macros to ppc4xx.h

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

These are used by both the SDRAM controller model and system DCRs. In preparation to move SDRAM controller in its own file move these macros to the ppc4xx.h header.

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.

ppc4xx_sdram: Rename functions to prevent name clashes

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

Rename functions to avoid name clashes when moving the DDR2 controller model currently called ppc440_sdram to ppc4xx_devs. This also more clearly shows which function belongs to which model.

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_sdram: QOM'ify

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

Change the ppc4xx_sdram model to a QOM class derived from the PPC4xx-dcr-device and name it ppc4xx-sdram-ddr. This is mostly modelling the DDR SDRAM controller found in the 440EP (used on the bamboo board) but also backward compatible with the older DDR controllers on some 405 SoCs so we also use it for those now. This likely does not cause problems for guests we run as the new features are just not accessed but to model 405 SoC accurately some features may have to be disabled or the model split between 440 and older. Newer SoCs (regardless of their PPC core, e.g. 405EX) may have an updated DDR2 SDRAM controller implemented by the ppc440_sdram model (only partially, enough for the 460EX on the sam460ex) that is not yet QOM'ified in this patch. That is intended to become ppc4xx-sdram-ddr2 when QOM'ified later.

ppc4xx_sdram: Move size check to ppc4xx_sdram_init()

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

Instead of checking if memory size is valid in board code move this check to ppc4xx_sdram_init() as this is a restriction imposed by the SDRAM controller.

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.

ppc4xx_sdram: Get rid of the init RAM hack

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

The do_init parameter of ppc4xx_sdram_init() is used to map memory regions that is normally done by the firmware by programming the SDRAM controller. Do this from board code emulating what firmware would do when booting a kernel directly from -kernel without a firmware so we can get rid of this do_init hack.

ppc4xx: Introduce Ppc4xxSdramBank struct

Instead of storing sdram bank parameters in unrelated arrays put them in a struct so it's clear they belong to the same bank and simplify the state struct using this bank type.
