Ethernet, switch, LEDs, buttons, USB, sysupgrade & LuCI were
successfully tested on BCM4706.
WARNING: Hack for BCM4710 adding BCM4710_PROTECTED_FILL_TLB() to the
local_r4k_flush_cache_sigtramp() could not be ported. That function has
been dropped in:
commit adcc81f148d7 ("MIPS: math-emu: Write-protect delay slot emulation pages")
commit 3315b6b336c8 ("MIPS: Delete unused flush_cache_sigtramp()")
it's unsure if that chipset will still work reliably.

Subject: [PATCH] pci: IDE fix
|
|
|
|
These are standard probing messages when using pdc202xx_old:
|
|
pdc202xx_old 0000:00:01.0: IDE controller (0x105a:0x0d30 rev 0x02)
|
|
PCI: Enabling device 0000:00:01.0 (0004 -> 0007)
|
|
PCI: Fixing up device 0000:00:01.0
|
|
0000:00:01.0: (U)DMA Burst Bit DISABLED Primary PCI Mode Secondary PCI Mode.
|
|
0000:00:01.0: FORCING BURST BIT 0x00->0x01 ACTIVE
|
|
pdc202xx_old 0000:00:01.0: 100% native mode on irq 6
|
|
|
|
With the default MAX_HWIFS value after above we get:
|
|
ide2: BM-DMA at 0x0400-0x0407
|
|
ide3: BM-DMA at 0x0408-0x040f
|
|
Probing IDE interface ide2...
|
|
hde: CF500, CFA DISK drive
|
|
|
|
As you can see it's ide2 + ide3 and hde.
|
|
|
|
With this patch applied we get:
|
|
ide0: BM-DMA at 0x0400-0x0407
|
|
ide1: BM-DMA at 0x0408-0x040f
|
|
Probing IDE interface ide0...
|
|
hda: CF500, CFA DISK drive
|
|
|
|
This fixes OpenWrt ticket #7061: https://dev.openwrt.org/ticket/7061
