18d9407a9f MFaltix:
Add support for Pre-Boot Virtual Memory (PBVM) to the loader.

PBVM allows us to link the kernel at a fixed virtual address without
having to make any assumptions about the physical memory layout. On
the SGI Altix 350 for example, there's no usuable physical memory
below 192GB. Also, the PBVM allows us to control better where we're
going to physically load the kernel and its modules so that we can
make sure we load the kernel in memory that's close to the BSP.

The PBVM is managed by a simple page table. The minimum size of the
page table is 4KB (EFI page size) and the maximum is currently set
to 1MB. A page in the PBVM is 64KB, as that's the maximum alignment
one can specify in a linker script. The bottom line is that PBVM is
between 64KB and 8GB in size.

The loader maps the PBVM page table at a fixed virtual address and
using a single translations. The PBVM itself is also mapped using a
single translation for a maximum of 32MB.

While here, increase the heap in the EFI loader from 512KB to 2MB
and set the stage for supporting relocatable modules.

e4623c22fe Fix mv_gpio_in() for pin numbers that occupy bits 8-31 in GPIO registers.
The compiler will truncate the 32-bit return value of mv_gpio_value_get()
to match the 8-bit return value of mv_gpio_in(). A conditional expression
is used to have mv_gpio_in() always return 0 or 1 instead.

6f181a80f8 Don't define IA64_PBVM_PAGE_SIZE as 1U shifted to the left by some amount.
The compiler seems to assume it's a 32-bit integral and rounding to the
page size using the standard expression (((u_long)(x) + mask) & ~mask),
results in a 32-bit value. Dropping the 'U' suffix is enough to have the
compiler treat the expression as a 64-bit integral.

c94018bcd8 o Deal with unmapped PBVM in the alternate instruction and data TLB fault
handlers.
o   Put the IVT in its own section and keep the supporting code close.
o   Make sure the VHPT is sized so that it can be mapped using a single
    translation.
o   Map the PAL code and VHPT with a translation that has the right size.
    Assume the platform has a PAL code size that can be mapped with a
    single translations.
o   Pass the pointer to the bootinfo structure as an argument to ia64_init().
o   Get rid of LOG2_ID_PAGE_SIZE and IA64_ID_PAGE_SIZE. It was used to map
    the regions 6 & 7 and was as large as possible. The problem is that we
    can't support memory attributes easily if the granuratity is not a page.
    We need to support memory attributes because the new USB stack violates
    the BUS_DMA(9) interface.
o   Update some comments...

NOTE:	this is broken for SMP kernels, because the AP startup code hasn't
	been updated yet.

df20f67447 Bring over the AR9285 board update code from ath9k.
This does a few things in particular:

* Abstracts out the gain control settings into a separate function;
* Configure antenna diversity, LNA and antenna gain parameters;
* Configure ob/db entries - the later v4k EEPROM modal revisions have
  multiple OB/DB parameters which are used for some form of
  calibration. Although the radio does have defaults for each,
  the EEPROM can override them.

This resolves the AR2427 related issues I've been seeing and makes
it stable at all 11g rates for both TX and RX.

72e1680189 o Make sure the page table has a size that is mappable. Certain page
sizes are not supported.
o   Map the PBVM page table.
o   Map the PBVM using the largest possible power of 2 that is less than
    the amount of PBVM used and round down to a valid page size. Note
    that the current kernel is between 8MB and 16MB in size, which would
    mean that 8MB would be the typical size of the mapping, if only 8MB
    wasn't an invalid page size. In practice, we end up mapping the first
    4MB of PBVM in most cases.

77b9efed7b Fix the nfarray offsets for the ar2133/ar5133 radio - (AR5416, AR9160, etc.)
The offsets didn't match the assumption that nfarray[] is ordered by the
chainmask bits and programmed via the register order in ar5416_cca_regs[].
This repairs that damage and ensures that chain 1 is programmed correctly.
(And extension channels will now be programmed correctly also.)

This fixes some of the stuck beacons I've been seeing on my AR9160/AR5416
setups - because Chain 1 would be programmed -80 or -85 dBm, which is
higher than the actual noise floor and thus convincing the radio that
indeed it can't ever transmit.

0d9aed8ad6 When injecting frames a temporary node is faked, during this several
uses of ic_curchan occur. Due to the nature of a scan, switching
channels constantly and all this happening without any kind of locks
held, it might happen that ic_curchan points to nowhere leading to
panics. Fix this by not allowing frame injections while in SCAN state.

759c594d37 Fix rmax calculation during BSS selection.
If multiple networks are available the max bandwidth is one
condition used for selecting the "best" BSS. To achieve that
we should consider all parameters which affect the max RX rate.
This includes 20/40MHz, SGI and the of course the MCS set.

If the TX MCS parameters are available we should use those,
because an AP announcing support for receiving frames at 450Mbps
might only be able to transmit at 150Mbps (1T3R). I haven't seen
devices with support for transmitting at higher rates then
receiving, so prefering TX over RX information should be safe.

While here, remove the hardcoded assumption that MCS15 is the max
possible MCS rate, use MCS31 instead which really is the highest
rate (according to the 802.11n std). Also, fix a mismatch of an
40MHz/SGI check.

d8e14b5eac Fill hc_mcsset completely.
Contrary to the rateset information in legacy frames the MCS Set
field also contains TX capability information in cases where the
number of available TX and RX spartial streams differ. Because a
rateset doesn't contain that information we have to pull the
those directly from the hardware capabilities.

bffb67e30f Change the way HT capatibilities are announced.
Get rid of the assumption that every device is capable of 40MHz,
SGI and 2 spartial streams. Instead of printing, in the worst case,
8 times 76 MCS rates, print logically connect ranges and the
support RX/TX streams.

A device without 40MHz and SGI support looks like:
ath0: 2T2R
ath0: 11na MCS 20Mhz
ath0: MCS 0-7: 6.5Mbps - 65Mbps
ath0: MCS 8-15: 13Mbps - 130Mbps

ath0: MCS 0-7: 6.5Mbps - 65Mbps

fbbe47a9ea First step on removing the harcoded RX/TX stream and MCS0-15 assumptions.
Initialize ic_rxstream/ic_txstream with 2, for compatibility reasons.
Introduce 4 new HTC flags, which are used in addition to ic_rxstream
and ic_txstream to compute the hc_mcsset content and also for initializing
ni_htrates. The number of spatial streams is enough to determine support
for MCS0-31 but not for MCS32-76 as well as some TX parameters in the
hc_mcsset field.
