* powerpc/mpc85xx: Add T4160 SoCYork Sun2013-05-14-0/+135
| | | | | | | | | | 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.

* e6500: Move L1 enablement after L2 enablementAndy Fleming2013-05-14-47/+47
| | | | | | | | | | 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. Signed-off-by: Andy Fleming <afleming@freescale.com>

| * Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

* | Replace __bss_end__ with __bss_endSimon Glass2013-03-15-6/+6
|/ | | | | | | | | | | | | Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>

The BSC9132 device combines Power Architecture e500 and DSP StarCore SC3850 core technologies with MAPLE-B2P baseband acceleration processing elements to address the need for a high performance, low cost, integrated solution that handles all required processing layers without the need for an external device except for an RF transceiver or, in a Micro base station configuration, a host device that handles the L3/L4 and handover between sectors. The BSC9132 SoC includes the following function and features: - Power Architecture subsystem including two e500 processors with 512-Kbyte shared L2 cache - Two StarCore SC3850 DSP subsystems, each with a 512-Kbyte private L2 cache - 32 Kbyte of shared M3 memory - The Multi Accelerator Platform Engine for Pico BaseStation Baseband Processing (MAPLE-B2P) - Two DDR3/3L memory interfaces with 32-bit data width (40 bits including ECC), up to 1333 MHz data rate - Dedicated security engine featuring trusted boot - Two DMA controllers - OCNDMA with four bidirectional channels - SysDMA with sixteen bidirectional channels - Interfaces - Four-lane SerDes PHY - PCI Express controller complies with the PEX Specification-Rev 2.0 - Two Common Public Radio Interface (CPRI) controller lanes - High-speed USB 2.0 host and device controller with ULPI interface - Enhanced secure digital (SD/MMC) host controller (eSDHC) - Antenna interface controller (AIC), supporting four industry standard JESD207/four custom ADI RF interfaces - ADI lanes support both full duplex FDD support & half duplex TDD - Universal Subscriber Identity Module (USIM) interface that facilitates communication to SIM cards or Eurochip pre-paid phone cards - Two DUART, two eSPI, and two I2C controllers - Integrated Flash memory controller (IFC) - GPIO - Sixteen 32-bit timers Signed-off-by: Naveen Burmi <NaveenBurmi@freescale.com> Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

| | | | | | | | By extracting these defines into a header, they can be re-used by other C sources as well. This will be done by the SPL framework OS boot support. Signed-off-by: Stefan Roese <sr@denx.de>

* powerpc/85xx: update the work-around for P4080 erratum SERDES-9Timur Tabi2012-11-27-7/+13
| | | | | | | | | | The documented work-around for P4080 erratum SERDES-9 has been updated. It is now compatible with the work-around for erratum A-4580. This requires adding a few bitfield macros for the BnTTLCRy0 register. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
* powerpc/p4080ds: fix PCI-e x8 link training down failureYuanquan Chen2012-11-27-0/+3
| | | | | | | | | | | | 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.

* powerpc/85xx: implement check for erratum A-004580 work-aroundTimur Tabi2012-11-27-0/+48
| | | | | | | | | | | | | | | | | | | The work-around for erratum A-004580 ("Internal tracking loop can falsely lock causing unrecoverable bit errors") is implemented via the PBI (pre-boot initialization code, typically attached to the RCW binary). This is because the work-around is easier to implement in PBI than in U-Boot itself. It is still useful, however, for the 'errata' command to tell us whether the work-around has been applied. For A-004580, we can do this by verifying that the values in the specific registers that the work-around says to update. This change requires access to the SerDes lane sub-structure in serdes_corenet_t, so we make it a named struct.

* powerpc/mpc85xx: Temporary fix for spin table backward compatibilityYork Sun2012-11-27-1/+46
| | | | | | | | | | | | Once u-boot sets the spin table to cache-enabled memory, old kernel which uses cache-inhibit mapping without coherence will not work properly. We use this temporary fix until kernel has updated its spin table code. For now this fix is activated by default. To disable this fix for new kernel, set environmental variable "spin_table_compat=no". After kernel has updated spin table code, this default shall be changed.
