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.
This patch fixes the PCIe card link up issue on T4240QDS.

Currently, the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" can enable
the master module of Boot from SRIO and PCIE on a platform. But this
is not a silicon feature, it's just a specific booting mode based on
the SRIO and PCIE interfaces. So it's inappropriate to put the macro
into the file arch/powerpc/include/asm/config_mpc85xx.h.
Change the macro "CONFIG_SYS_FSL_SRIO_PCIE_BOOT_MASTER" to
"CONFIG_SRIO_PCIE_BOOT_MASTER", remove them from
arch/powerpc/include/asm/config_mpc85xx.h file, and add those macros
in configuration header file of each board which can support the
master module of Boot from SRIO and PCIE.

Due to SerDes configuration error, if we set the PCI-e controller link width
as x8 in RCW and add a narrower width(such as x4, x2 or x1) PCI-e device to
PCI-e slot, it fails to train down to the PCI-e device's link width. According
to p4080ds errata PCIe-A003, we reset the PCI-e controller link width to x4 in
u-boot. Then it can train down to x2 or x1 width to make the PCI-e link between
RC and EP.

Currently, the SRIO and PCIE boot master module will be compiled into the
u-boot image if the macro "CONFIG_FSL_CORENET" has been defined. And this
macro has been included by all the corenet architecture platform boards.
But in fact, it's uncertain whether all corenet platform boards support
this feature.
So it may be better to get rid of the macro "CONFIG_FSL_CORENET", and add
a special macro for every board which can support the feature. This
special macro will be defined in the header file
"arch/powerpc/include/asm/config_mpc85xx.h". It will decide if the SRIO
and PCIE boot master module should be compiled into the board u-boot image.

Introduce CONFIG_PCI_ENUM_ONLY variable for platforms that just want a
quick enumberation of the PCI devices, but don't need any setup work done.
This is very beneficial on platforms that have u-boot loaded by another
boot loader which does a more sophisticated job of setup of PCI devices
than u-boot. That way, u-boot can just read what's there and get on
with life. This is what SeaBIOS does.

For the powerpc processors with PCIE interface, boot location can be
configured from one PCIE interface by RCW. The processor booting from PCIE
can do without flash for u-boot image. The image can be fetched from another
processor's memory space by PCIE link connected between them.
The processor booting from PCIE is slave, the processor booting from normal
flash memory space is master, and it can help slave to boot from master's
memory space.
When boot from PCIE, slave's core should be in holdoff after powered on for
some specific requirements. Master will release the slave's core at the
right time by PCIE interface.
Environment and requirement:
master:
1. NOR flash for its own u-boot image, ucode and ENV space.
2. Slave's u-boot image is in master NOR flash.
3. Normally boot from local NOR flash.
4. Configure PCIE system if needed.
slave:
1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
2. Boot location should be set to one PCIE interface by RCW.
3. RCW should configure the SerDes, PCIE interfaces correctly.
4. Must set all the cores in holdoff by RCW.
5. Must be powered on before master's boot.
For the master module, need to finish these processes:
1. Initialize the PCIE port and address space.
2. Set inbound PCIE windows covered slave's u-boot image stored in
master's NOR flash.
3. Set outbound windows in order to configure slave's registers
for the core's releasing.
4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2"
or "PCIE3" using the following command:
setenv bootmaster PCIE1
saveenv

The FSL PCI driver uses local prototypes for

PCI cards might need some time after reset to respond. On some
boards (mpc5200 or mpc8260 based) the PCI bus reset is deasserted
at pci_init_board() time, so we currently can not use available
"pcidelay" option for waiting before PCI bus scan since this
waiting takes place before calling pci_init_board(). By moving
the pcidelay code to the new location using of the "pcidelay"
option is possible on mpc5200 or mpc8260 based boards, too.
Since pci_hose_scan() could be called multiple times, restrict
the function to wait only during its first call and to ignore
pcidelay for any further call (as pointed out by Matthias).

FSL PCIe controller v2.1:
- New MSI inbound window
- Same Inbound windows address as PCIe controller v1.x
Added new pit_t member(pmit) to struct ccsr_pci for MSI inbound window
FSL PCIe controller v2.2 and v2.3:
- Different addresses for PCIe inbound window 3,2,1
- Exposed PCIe inbound window 0
- New PCIe interrupt status register
Added new Interrupt Status register to struct ccsr_pci & updated pit_t array
size to reflect the 4 inbound windows.
To maintain backward compatiblilty, on V2.2 or greater controllers we
start with inbound window 1 and leave inbound 0 with its default value
(which maps to CCSRBAR).

This change does the following:
- Adds printing of negotiated link width. This information can be
useful when debugging PCIe issues.
- Makes it optional for boards to implement board_serdes_name().
Previously boards that did not implement it would print unsightly
output such as "PCIE1: Connected to <NULL>..."
- Rewords the PCIe boot output to reduce line length and to make it
clear that the "base address XYZ" value refers to the base address of
the internal processor PCIe registers and not a standard PCI BAR
value.
- Changes "PCIE" output to the standard "PCIe"
Before change:

Since all the PCIe controllers are connected over SERDES on the SoCs we
can utilize is_serdes_configured() to determine if a controller is
enabled. After which we can setup the ATMUs and LAWs for the controller
in a common fashion and allow board code to specify what the controller
is connected to for reporting reasons.
We also provide a per controller (rather than all) for some systems that
may have special requirements.
Finally, we refactor the code used by the P1022DS to utilize the new
generic code.

Previously we passed in a specifically named struct pci_controller to
determine if we had setup the particular PCI bus. Now we can search for
the struct so we dont have to depend on the name or the struct being
statically allocated.
Introduced new find_hose_by_cfg_addr() to get back a pci_controller struct
back by searching for it means we can do things like dynamically allocate
them or not have to expose the static structures to all users.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Move the printing of PCI device information to before the PCI device is
configured. This prevents the case where recursive scanning results in
the deepest devices being printed first.
This change also makes PCI lockups during enumeration easier to
diagnose since the device that is being configured is printed out prior
to configuration. Previously, it was not possible to determine which
device caused the PCI lockup.
Original example:
PCIE1: connected as Root Complex
04:01.0 - 8086:1010 - Network controller
04:01.1 - 8086:1010 - Network controller

This change does the following:
- Removes the printing of the PCI interrupt line value. This is
normally set to 0 by U-Boot on bootup and is rarely used during
everyday operation.
- Prints out the PCI function number of a device. Previously a device
with multiple functions would be printed identically 2 times, which is
generally confusing. For example, on an Intel 2 port gigabit Ethernet
card the following was displayed:
...
04 01 8086 1010 0200 00
04 01 8086 1010 0200 00
...
- Prints a text description of each device's PCI class instead of the
raw PCI class code. The textual description makes it much easier to
determine what devices are installed on a PCI bus.
- Changes the general formatting of the PCI device output.

Previously fsl_pci_init_port() always assumed that a port was a PCIe
port and would incorrectly print messages for a PCI port such as the
following on bootup:
PCI1: 32 bit, 33 MHz, sync, host, arbiter
Scanning PCI bus 00
PCIE1 on bus 00 - 00
This change corrects the output of fsl_pci_init_port():
PCI1: 32 bit, 33 MHz, sync, host, arbiter
Scanning PCI bus 00
PCI1 on bus 00 - 00

Add a new 'pci enum' command which re-enumerates the PCI buses. This
command is enabled via the CONFIG_CMD_PCI_ENUM define and can be useful
in boards with FPGAs connected via PCI/PCIe, boards that support PCI
hot-plugging, or during PCI debug.
Also enable the 'pci enum' command for X-ES's Freescale-based boards.

Previously we used an alias the pci node to determine which node to
fixup or delete. Now we use the new fdt_node_offset_by_compat_reg to
find the node to update.
Additionally, we replace the code in each board with a single macro call
that makes assumes uniform naming and reduces duplication in this area.

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

If the PCI controller wasn't configured or enabled delete from the
device tree (include its alias).
For the case that we didn't even configure u-boot with knowledge of
the controller we can use the fact that the pci_controller pointer
is NULL to delete the node in the device tree. We determine that
a controller was not setup (because of HW config) based on the fact
that cfg_addr wasn't setup.

The list of 4xx SoCs that should send type 1 PCI transactions
is not defined correctly. As a result PCI-PCI bridges and devices
behind them are not identified. The following 4xx variants should
send type 1 transactions: 440GX, 440GP, 440SP, 440SPE, 460EX and 460GT.
