Re[3]: pccbb pccard rman - Something is very wrong somewhere

Mauritz,

CURRENT is checking for allocated memory yet (see messages: region is
allocated).

cbb0 is initialized and get the first 0x88000000 (pccbb.c. #define
CBB_START_MEM	0x88000000):

cbb0: <TI1225 PCI-CardBus Bridge> at device 3.0 on pci0
rman_reserve_resource: <I/O memory addresses> request: [0x88000000,
0xffffffff], length 0x1000, flags 12288, device cbb0
considering [0, 0xf3ffffff]
truncated region: [0x88000000, 0xf3ffffff]; size 0x6c000000 (requested
0x1000)
candidate region: [0xf3ffffff, 0x88000000], size 0x6c000000
splitting region in three parts: [0, 0x87ffffff]; [0x88000000, 0x88000fff];
[0x88001000, 0xf3ffffff]
cbb0: PCI Memory allocated: 88000000

later, ccb1 is initilized and get 0x88001000:

cbb1: <TI1225 PCI-CardBus Bridge> at device 3.1 on pci0
rman_reserve_resource: <I/O memory addresses> request: [0x88000000,
0xffffffff], length 0x1000, flags 12288, device cbb1
considering [0x88000000, 0x88000fff]
region is allocated
considering [0x88001000, 0xf3ffffff]
truncated region: [0x88001000, 0xf3ffffff]; size 0x6bfff000 (requested
0x1000)
candidate region: [0xf3ffffff, 0x88001000], size 0x6bfff000
allocating from the beginning
cbb1: PCI Memory allocated: 88001000

later... PCCARD ask for resources to cbb (dependant) and obtain 0x88002000:

pccard0: read_cis
rman_reserve_resource: <I/O memory addresses> request: [0x88000000,
0xffffffff], length 0x400, flags 12288, device pccard0

I'm not an expertinto this but if you, after boot, change value
hw.cbb.start_memory to any non aligned value (to 0x10000) it will fail.
Also, you can workaround the error if you define in hint something like:
hw.cbb.start_memory="0x87FFE000", that lets 0x87FFE000 to cbb0, 0x87FFF000
to cbb1 and 0x88000000 to pccard0 that makes this aligned.

So I really think that pccard allocation needs alignment to 0x10000, I
don't know exactly why.

Carlos Velasco
