Revert "pci: Scale MAX_PCI_REGIONS based on CONFIG_NR_DRAM_BANKS"

2019-05-08T05:02:10Z

This reverts commit aec4298ccb337106fd0115b91d846a022fdf301d. Unfortunately this has a dramatic impact on the pre-relocation memory used on x86 platforms (increasing it by 2KB) since it increases the overhead for each PCI device from 220 bytes to 412 bytes. The offending line is in UCLASS_DRIVER(pci): .per_device_auto_alloc_size = sizeof(struct pci_controller), This means that all PCI devices have the controller struct associated with them. The solution is to move the regions[] member out of the array, makes its size dynamic, or split UCLASS_PCI into controllers and non-controllers, as the comment suggests. For now, revert the commit to get things running again. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

pci: Scale MAX_PCI_REGIONS based on CONFIG_NR_DRAM_BANKS

2019-04-23T21:57:23Z

If a platform defines CONFIG_NR_DRAM_BANKS, each DRAM bank will be added as a PCI region. The number of MAX_PCI_REGIONS therefore needs to scale with the number of DRAM banks, otherwise we will end up with too little space in the hose->regions array to store all system memory regions.
