* gPeripheralBase keeps track of the device
peripherals before and after mmu_init
* Add ability to disable mmu for troubleshooting
* Remove static FB_BASE, we actually don't know
where the FB is yet. (depends on firmware used)
If Haiku has the hostname set, inform DHCP server with corresponding
option in DHCPDISCOVER and DHCPREQUEST messages. That should simplify
accessing Haiku hosts by using it's hostname instead of raw addresses.
* BCM2708 defines no longer assume 0x20 address
We will be throwing away the blob memory mapping
and using our own.
* Use existing blob mapping to turn GPIO led on pre mmu_init
* Remap MMU hardware addresses from 0x7E. We could map each device,
however the kernel will throw away the mappings again anyway. For
now we just map the whole range and use offsets.
* Serial uart no longer works, however at least
we know why now :). Serial driver now needs to
use mapped address.
* Use U-Boot mmu code as base
* This will be factored out someday into common arch mmu
code when we can read Flattened Device Trees
* Move mmu_init after serial_init.
Temporary change as we will want serial_init to use
memory mapped addresses... for debugging.
* since we include BoardSetup earlier now, the TARGET_* flags were discarded. Use HAIKU_* instead.
* Add variables to hold the default entry point and the desired uimage OS emulation.
* introduce a DebugUART baseclass,
* rework 8250 and PL011 implementations from kallisti5 to inherit DebutUART,
* each arch should override the IO methods to access registers.
* on ARM registers are 32bit-aligned.
* U-Boot still works for the verdex target.
* rPi still compiles, needs testing.
* Still some more consolidation needed to allow runtime choice of the UART type (as read from FDT blobs for ex.).
* serial.cpp should probably mostly be made generic as well.
* didn't touch x86 or ppc yet.
* Pi firmware was updated to note that Broadcom
had to be included with firmware blobs.
* While we have permission from Eben to have the
blobs in-tree, they are now offically on github
in a fixed location removing the need to have
these in-tree.
* Clean up BoardConfig, note firmware URL and
files needed
* Update info.txt with how Haiku boot process works
* Lets wait for space *before* writing to the fifo
instead of after.
* Flush functions now really flush the fifo waiting
for them to enter an empty state.
* Simple memory barriers added (may need revised)
We don't have access to the kernel barriers here.
