[U-Boot] [Patch v2, batch 2 01/23] powerpc/B4860: Corrected FMAN1 operating frequency print at u-boot

[York Sun]

From: Sandeep Singh <sandeep@freescale.com>

The bit positions for FMAN1 freq in RCW is different for B4860.
Also addded a case when FMAN1 frewuency is equal to systembus.

[U-Boot] [Patch v2, batch 2 02/23] powerpc/mpc85xx: Add definitions for HDBCR registers

[York Sun]

From: Andy Fleming <afleming@freescale.com>

Makes it a bit easier to see if we've properly set them. While
we're in there, modify the accesses to HDBCR0 and HDBCR1  to actually
use those definitions.

[U-Boot] [Patch v2, batch 2 03/23] powerpc/pcie: add PCIe version 3.x support

[York Sun]

From: Roy ZANG <tie-fei.zang@freescale.com>

T4240 PCIe IP is version 3.0 and has some update comparing previous
QorIQ products.

1.  Move Freescale specific register define
to
arch/powerpc/include/asm/fsl_pci.h
and update the register offset define for T4240.

2. add the status/control register define
use status/control register to judge the link status

3. The original code uses 'Programming Interface' field to judge if PCIE is
EP or RC mode, however, T4240 does not support this functionality.
According to PCIE specification, 'Header Type' offset 0x0e is used to
indicate header type, so for PCIE controller, the patch changes code to
use 'Header Type' field to identify if the PCIE is RC or EP mode.

We can't do it that way. I can't apply a patch which is known to break the
build -- it breaks bisectability. Roy, please submit a new patch which
works correctly for all platforms

However, the linked patch looks very much like a temporary workaround.
Clearly, 83xx needs some of the same definitions as 85xx, and making 2
copies isn't the solution. Somehow, they need to share the definitions. I'm
not entirely clear on why 83xx has its own pci code, but it's very
misleading to call the 85xx PCI code "fsl_pci", and leave out 83xx, even
though it shares some of the same code. Please propose a solution which
acknowledges and accommodates this shared functionality.

[U-Boot] [Patch v2, batch 2 06/23] e6500: Move L1 enablement after L2 enablement

[York Sun]

From: Andy Fleming <afleming@freescale.com>

The L1 D-cache on e6500 is write-through. This means that it's not
considered a good idea to have the L1 up and running if the L2 is
disabled. We don't actually *use* the L1 until after the L2 is
brought up on e6500, so go ahead and move the L1 enablement after
that code is done.

[York Sun]

Update the timing table to support more rank density, based on the theory
that similar density DIMMs have similar clock adjust and write level start
timing. Update the timing for 1600 and 1866 MT/s. Tested with Micron
MT18JSF1G72AZ-1G9E1 DIMMs, iDIMM M3CN-4GMJ3C0C-M92.

[U-Boot] [Patch v2, batch 2 15/23] T4/USB: Add USB 2.0 UTMI dual phy support

[York Sun]

From: Roy Zang <tie-fei.zang@freescale.com>

T4240 internal UTMI phy is different comparing to previous UTMI PHY
in P3041.
This patch adds USB 2.0 UTMI Dual PHY new memory map and enable it for
T4240.
The phy timing is very sensitive and moving the phy enable code to
cpu_init.c will not work.

I get a build error whenever the code attempts to use ccsr_usb_phy_t. Was
this even build-tested? Am I going to find a later patch that fixes this?
Am I running into a compiler version thing, where it's ok to do struct foo
{ } foo_t, without "typedef" before? My impression is that's just for C++...

I'm going to add "typedef" before this struct, and apply the patch, but
please be more careful.

When CONFIG_SYS_FSL_QORIQ_CHASSIS2 is not defined, QMAN frequency will not

Can we just move the original copy of the above lines out of the #ifdef? I
don't see any reason to do it the same way in two places.

You mean delete #ifdef? It will have a compiling error, won't it? See
include/e500.h, the freqQMAN is withing #ifdef.

T4160 SoC is low power version of T4240. The T4160 combines eight dual
threaded Power Architecture e6500 cores and two memory complexes (CoreNet
platform cache and DDR3 memory controller) with the same high-performance
datapath acceleration, networking, and peripheral bus interfaces.

[U-Boot] [Patch v2, batch 2 23/23] powerpc: Add T4160QDS

[York Sun]

T4160QDS shares the same platform as T4240QDS. T4160 is a low power
version of T4240, with eight e6500 cores, two DDR3 controllers, and
slightly different SerDes protocols.
