1b72dbecca ppc/85xx: Don't enable interrupts before we're ready
We cannot handle any exceptions while running in AS1, as the exceptions
will transition back to AS0 without a valid mapping.

6c97a20d0b ppc/85xx: Introduce RESET_VECTOR_ADDRESS to handle non-standard link address
Some board ports place TEXT_BASE at a location that would cause the
RESET_VECTOR_ADDRESS not to be at 0xfffffffc when we link.  By default
we assume RESET_VECTOR_ADDRESS will be 0xfffffffc if the board doesn't
explicitly set it.

c348322ac7 ppc/85xx: Clean up do_reset
There is no reason to do a run time check for e500 v1 based cores to
determine if we have the GUTs RSTCR facility.  Only the first generation
of PQ3 parts (MPC8540/41/55/60) do not have it.  So checking to see if
we are e500 v2 would miss future parts (like e500mc).

Just change this to be ifdef'd based on CONFIG_MPC85{40,41,55,60}.

c725908681 ppc/85xx: Fix bug in setup_mp code
Its possible that we try and copy the boot page code out of flash into a
DDR location that doesn't have a TLB cover it.  For example, if we have
3G of DDR we typically only map the first 2G.  In the cases of 4G+ this
wasn't an issue since the reset page TLB mapping covered the last page
of memory which we wanted to copy to.

We now change the physical address of the reset page TLB to map to the
true physical location of the boot page code, copy and than set the
TLB back to its 1:1 mapping of the reset page.

26f4cdba6b 85xx: Add support for setting IVORs to fixed offset defaults

e393e2e9bc 85xx: Fix addrmap to include memory
When we init the addrmap based on the TLB we will not end up getting
the TLB that covers memory if we are using SPD.  The reason is we
haven't relocated at the point that we setup the memory TLB and thus it
will not get setup in the addrmap.

Instead we can just walk over the TLB array after we've relocated and
see all the TLBs that have been set and use that information to populate
the initial addrmap.  By doing this we insure that we get the TLB
entries that cover memory.

The following changes were made to sync up the DMA code between the 85xx

85xx:
- Don't set STRANSINT and SPCIORDER fields in SATR register.  These bits
  only have an affect when the SBPATMU bit is set.
- Write 0xffffffff instead of 0xfffffff to clear errors in the DMA
  status register.  We may as well clear all 32 bits of the register...

86xx:
- Add CONFIG_SYS_MPC86xx_DMA_ADDR define to address DMA registers
- Add clearing of errors in the DMA status register when initializing
  the controller
- Clear the channel start bit in the DMA mode register after a transfer

ada591d2a0 mpc8[56]xx: Put localbus clock in sysinfo and gd
Currently MPC85xx and MPC86xx boards just calculate the localbus frequency
and print it out, but don't save it.

This changes where its calculated and stored to be more consistent with the
CPU, CCB, TB, and DDR frequencies and the MPC83xx localbus clock.

The localbus frequency is added to sysinfo and calculated when sysinfo is
set up, in cpu/mpc8[56]xx/speed.c, the same as the other frequencies are.

get_clocks() copies the frequency into the global data, as the other
frequencies are, into a new field that is only enabled for MPC85xx and
MPC86xx.

checkcpu() in cpu/mpc8[56]xx/cpu.c will print out the local bus frequency
from sysinfo, like the other frequencies, instead of calculating it on the
spot.

f51f07eb58 85xx: Fix the boot window issue
If one custom board is using the 8MB flash, it is set
as FLASH_BASE = 0xef000000, TEXT_BASE = 0xef780000.
The current start.S code will be broken at switch_as.

It is because the TLB1[15] is set as 16MB page size,
EPN = TEXT_BASE & 0xff000000, RPN = 0xff000000.

For the 8MB flash case, the EPN = 0xefxxxxxx,
RPN = 0xffxxxxxx. Assume the virt address of switch_as
is 0xef7ff18c, the real address of the instruction at
switch_as should be 0xff7ff18c. the 0xff7ff18c is out
of the range of the default 8MB boot LAW window
0xff800000 - 0xffffffff.

So when we switch to AS1 address space at switch_as,
the core can't fetch the instruction at switch_as any
more. It will cause broken issue.

181a365011 Set IVPR to kenrel entry point in second core boot page
Assuming the OSes exception vectors start from the base of kernel address, and
the kernel physical starting address can be relocated to an non-zero address.
This patch enables the second core to have a valid IVPR for debugger before
kernel setting IVPR in CAMP mode. Otherwise, IVPR is 0x0 and it is not a valid
value for second core which runs kernel at different physical address other
than 0x0.

a5d212a263 mpc8xxx: LCRR[CLKDIV] is sometimes five bits
On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits
instead of four.

In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems.  It
should be safe as the fifth bit was defined as reserved and set to 0.

Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

58ec4866ed mpc8[56]xx: Put localbus clock in device tree
Export the localbus frequency in the device tree, the same way the CPU, TB,
CCB, and various other frequencies are exported in their respective device
tree nodes.

Some localbus devices need this information to be programed correctly, so
it makes sense to export it along with the other frequencies.

Unfortunately, when someone wrote the localbus dts bindings, they didn't
bother to define what the "compatible" property should be.  So it seems no
one was quite sure what to put in their dts files.

Based on current existing dts files in the kernel source, I've used
"fsl,pq3-localbus" and "fsl,elbc" for MPC85xx, which are used by almost all
of the 85xx devices, and are looked for by the Linux code.  The eLBC is
apparently not entirely backward compatible with the pq3 LBC and so eLBC
equipped platforms like 8572 won't use pq3-localbus.

For MPC86xx, I've used "fsl,elbc" which is used by some of the 86xx systems
and is also looked for by the Linux code.  On MPC8641, I've also used
"fsl,mpc8641-localbus" as it is also commonly used in dts files, some of
which don't use "fsl,elbc" or any other acceptable name to match on.

ae5f943ba8 85xx: Fix the incorrect register used for DDR erratum1
The 8572 DDR erratum1:
DDR controller may enter an illegal state when operating
in 32-bit bus mode with 4-beat bursts.

Description:
When operating with a 32-bit bus, it is recommended that
DDR_SDRAM_CFG[8_BE] is cleared when DDR2 memories are used.
This forces the DDR controller to use 4-beat bursts when
communicating to the DRAMs. However, an issue exists that
could lead to data corruption when the DDR controller is
in 32-bit bus mode while using 4-beat bursts.

Projected Impact:
If the DDR controller is operating in 32-bit bus mode with
4-beat bursts, then the controller may enter into a bad state.
All subsequent reads from memory is corrupted.
Four-beat bursts with a 32-bit bus only is used with DDR2 memories.
Therefore, this erratum does not affect DDR3 mode.

Work Arounds:
To work around this issue, software must set DEBUG_1[31] in
DDR memory mapped space (CCSRBAR offset + 0x2f00 for DDR_1
and CCSRBAR offset + 0x6f00 for DDR_2).

Currenlty, the code is using incorrect register DDR_SDRAM_CFG_2
as condition, but it should be DDR_SDRAM_CFG register.

	ASSIGN_ADDRESSES
	COMPUTE_REGS
