Based upon original patch by Herbert Xu, which contained
the following problem description:
--------------------
When the forward delay is set to zero, we still delay the setting
of the forwarding state by one or possibly two timers depending
on whether STP is enabled. This could either turn out to be
instantaneous, or horribly slow depending on the load of the
machine.
As there is nothing preventing us from enabling forwarding straight
away, this patch eliminates this potential delay by executing the
code directly if the forward delay is zero.
The effect of this problem is that immediately after the carrier
comes on a port, the bridge will drop all packets received from
that port until it enters forwarding mode, thus causing unnecessary
packet loss.
Note that this patch doesn't fully remove the delay due to the
link watcher. We should also check the carrier state when we
are about to drop an incoming packet because the port is disabled.
But that's for another patch.
--------------------
This version of the fix takes a different approach, in that
it just does the state change directly.

radeon: misc corrections
I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that
hangs in my sparc64 boxes when the init scripts set the font. The problem
goes away if I disable acceleration.
I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.
1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
and the XORG video driver differ. I've made the kernel
match what XORG is using.
2) In radeonfb_engine_reset() we have top-level code structure
that roughly looks like:
if (family is 300, 350, or V350)
do this;
else
do that;
...
if (family is NOT 300, OR
family is NOT 350, OR
family is NOT V350)
do another thing;
this last conditional makes no sense, is always true,
and obviously was likely meant to be "family is NOT
300, 350, or V350". So I've made the code match the
intent.

OMAP2/3 clock: combine clkdm, clkdm_name into union in struct clk
struct clk contains a struct clockdomain *clkdm and const char
*clkdm_name. The clkdm_name is only used at initialization to look up
the appropriate clkdm pointer. Combining these into a union saves
about 850 bytes on 3430SDP. This patch should not cause any change in
kernel function.
Boot-tested on 3430SDP ES2; compile-tested with n800_defconfig.

OMAP3 clock: add omap3_core_dpll_m2_set_rate()
Add the omap3_core_dpll_m2_set_rate() function to the OMAP3 clock code,
which calls into the SRAM function omap3_sram_configure_core_dpll() to
change the CORE DPLL M2 divider. (SRAM code is necessary since rate changes
on clocks upstream from the SDRC can glitch SDRAM accesses.)
Use this function for the set_rate function pointer in the dpll3_m2_ck
struct clk. With this function in place, PM/OPP code should be able to
alter SDRAM speed via code similar to:
clk_set_rate(&dpll3_m2_ck, target_rate).

OMAP3 clock/SRAM: fix CORE DPLL M2 divider mask
3430ES2+ CORE DPLL M2 divider can divide by 1 to 31, unlike ES1, which
was more limited. The SRAM code currently only supports dividing by 1
or 2, but we should mask off the full range of bits to guard against
the event that the previous contents of CM_CLKSEL_PLL1 included an M2
divider > 2.

OMAP2 SDRC: add timing data for Micron MT46H32M32LF-6
Add timing data for the Micron MT46H32M32LF-6 SDRAM chip, used on the
OMAP3 Beagle and EVM boards. Original timing data is from the Micron
datasheet PDF downloaded from:
For a given SDRAM clock rate, SDRAM chips require memory controllers
to use a specific set of timing minimums and maximums to transfer data
reliably. These parameters can be different for different memory chips
and can also potentially vary by board.
This patch adds the infrastructure for board-*.c files to pass this
timing data to the SDRAM controller init function. The timing data is
specified in an 'omap_sdrc_params' structure, in terms of SDRC
controller register values. An array of these structs, one per SDRC
target clock rate, is passed by the board-*.c file to
omap2_init_common_hw().
This patch does not define the values for different memory chips, nor
does it use the values for anything; those will come in subsequent patches.

OMAP2 SDRC: separate common OMAP2/3 code from OMAP2xxx code
Separate SDRC code common to OMAP2/3 from mach-omap2/sdrc2xxx.c to
mach-omap2/sdrc.c. Rename the OMAP2xxx-specific functions to use an
'omap2xxx' prefix rather than an 'omap2' prefix, and use "sdrc" in the
function names rather than "memory." Mark several functions
as static that should not be used outside the sdrc2xxx.c file.
