2012-05-16bcma: Move initialization of SPROM to prevent overwriteNathan Hintz
The first thing bcm47xx_fill_sprom does is initialize (zero fill) the SPROM. For BCMA SOC, this wipes out any values previously read by bcm47xx_fill_sprom_ethernet (see arch/mips/bcm47xx/setup.c - bcm47xx_get_sprom_bcma). Move the initialization of SPROM so it is called prior to filling in any values. Signed-off-by: Nathan Hintz <nlhintz@hotmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-05-16MIPS: bcm47xx: read baordrev without prefix from spromHauke Mehrtens

2012-05-16ssb: remove rev from boardinfoHauke Mehrtens
Previously the rev contained the revision read from the pci config space and was used as board_rev in the wireless drivers. This is wrong the board_rev is only fetched from the sprom accordingly to the open source part of the Broadcom SDK and brcmsmac. This patch removes the rev from the boardinfo structure and uses the board_rev attribute from sprom instead. This attribute is filled by PCI, PCMCIA, SDIO and SoC code.

2012-05-15MIPS: ath79: add a workaround for a PCI controller bug in AR7240 SoCsGabor Juhos
The PCI controller of the AR724X SoCs has a hardware bag. If the BAR0 register of the PCI device is set to the proper base address, the memory address space of the device is not accessible. When the device driver tries to access the memory address space of the PCI device, it leads to data bus error, similiar to this: Data bus error, epc == 801f69a0, ra == 801f698c Oops[#1]: Cpu 0 $ 0 : 00000000 00000061 deadbeef 000000ff $ 4 : 00000000 000000ff 00000014 00000000 $ 8 : ff000000 fffffffc 00000000 00000000 $12 : 000001f5 00000006 00000000 6e637920 $16 : 81ca4000 81ca0260 81ca4000 804d70f0 $20 : fffffff4 0000002b 803ad4c4 00000000 $24 : 00000003 00000000 $28 : 81c20000 81c21c60 00000000 801f698c Hi : 00000000 Lo : 00000000 epc : 801f69a0 ath9k_hw_init+0xd0/0xa70 Not tainted ra : 801f698c ath9k_hw_init+0xbc/0xa70 Status: 1000c103 KERNEL EXL IE Cause : 1080001c PrId : 00019374 (MIPS 24Kc) Modules linked in: Process swapper (pid: 1, threadinfo=81c20000, task=81c18000, tls=00000000) Stack : 00000000 00000000 00000000 00000000 81c21c78 81ca0260 00000000 804d70f0 81ca0260 81c21cc0 81ca0e80 81ca0260 81ca4000 804d70f0 fffffff4 0000002b 803ad4c4 00000000 00000000 801e3ae8 81c9d080 81ca0e80 b0000000 800b9b9c 00000008 81c9d000 8031aeb0 802d38a0 00000000 81c14c00 81c14c60 00000000 81ca0e80 81ca0260 b0000000 801f08a4 81c9c820 81c21d48 81c9c820 80144320 ...

2012-05-15MIPS: ath79: fix broken ar724x_pci_{read,write} functionsGabor Juhos
The current ar724x_pci_{read,write} functions are broken. Due to that, pci_read_config_byte returns with bogus values, and pci_write_config_{byte,word} unconditionally clears the accessed PCI configuration registers instead of changing the value of them. The patch fixes the broken functions, thus the PCI configuration space can be accessed correctly.
