* powerpc/mpc83xx: set TXEQA/TXEQE value for mpc837XE sataJerry Huang2011-12-12-1/+10
| | | | | | | | | | | | In the current u-boot code, the value of these fields are the reserved value (0b100), through the signal integrity measurement on freescale's board with these reserved setting, the signal eye is out of the recommended spec for non-transition amplitude at 500mV nominal. According to the errata for MPC8379E, we should make a change to the recommended setting from essentially nothing at this time to 0b001 for SATA.

* powerpc/bootm: Flush ramdisk and device tree image when booting on MPKumar Gala2011-12-12-6/+16
| | | | | | | | | | | | | We already flush the kernel image after we've loaded it to ensure visiblity to the other cores. We need to do the same thing for the ramdisk and device tree images. In AMP boot scenarios we might not be HW cache coherent with the secondary core that we are loading and setting the ramdisk and device tree up for. Thus we need to ensure we've flushed the regions of memory utilized by ramdisk and device tree so the loadding and any modifications (from decompression or fdt updates) are made visible to the secondary cores.

* powerpc: Minimal private libgcc to build on DebianKyle Moffett2011-12-07-1/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Standard Debian powerpc and powerpcspe systems only include hard-float libgcc in their native compilers, which causes scary build warnings when building U-Boot. Debian and other PowerPC-supporting distributions used to provide libgcc and other libraries in a "nof" (soft-float) form in the "multilib" packages. As they were completely unused by the distribution and therefore tended to be very buggy it was decided to save some time on the part of the maintainers and build-servers by removing them. Admittedly, right now the linker warnings do not indicate any problems, as the included routines do not use any floating point at all. The concern is that if floating-point code were ever added it might cause hard-float code to be unexpectedly included in U-Boot without generating a hard error. This would cause unexplained crashes or indeterminate results at runtime. The easiest way to resolve this is to borrow the routines that U-Boot needs from the Linux kernel, which has the same issue. Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3(). They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5, commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+. The Makefile framework was copied from the U-Boot ARM port.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Freescale COM Express P2020 board. This board is similar to the P1_P2_RDB, but has some extra (as well as missing) peripherals. Unlike all other mpc85xx boards, it uses a watchdog timeout to reset. Using the HRESET_REQ register does not work. This board has no NOR flash, and can only be booted via SD or SPI. This procedure is documented in Freescale Document Number AN3659 "Booting from On-Chip ROM (eSDHC or eSPI)." Some alternative documentation is provided in Freescale Document Number P2020RM "P2020 QorIQ Integrated Processor Reference Manual" (section 4.5). Signed-off-by: Ira W.

* | powerpc/85xx: verify the localbus device tree address before booting the OSTimur Tabi2011-11-29-9/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The localbus controller node in the device tree is typically a root node, even though the controller is part of CCSR. If we were to put the lbc node under the SOC node, then the 'ranges' property in the lbc node would translate through the 'ranges' property of the parent SOC node, and we don't want that. Since the lbc is a separate node, it's possible for the 'reg' property to be wrong. This happened with the original version of p1022ds.dts, which used a 32-bit value in the 'reg' address, instead of a 36-bit address.

* | powerpc/85xx: clean up and document the QE/FMAN microcode macrosTimur Tabi2011-11-29-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several macros are used to identify and locate the microcode binary image that U-boot needs to upload to the QE or Fman. Both the QE and the Fman use the QE Firmware binary format to package their respective microcode data, which is why the same macros are used for both. A given SOC will only have a QE or an Fman, so this is safe. Unfortunately, the current macro definition and usage has inconsistencies. For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address of NAND. There's no way to know by looking at a variable how it's supposed to be used. In the future, the code which uploads QE firmware and Fman firmware will be merged.

* | powerpc/85xx: always implement the work-around for Erratum SATA_A001Timur Tabi2011-11-29-4/+33
| | | | | | | | | | | | | | | | | | | | On the P1022/P1013, the work-around for erratum SATA_A001 was implemented only if U-Boot initializes SATA, but SATA is not initialized by default. So move the work-around to the CPU initialization function, so that it's always executed on the SOCs that need it.

| | | | | | | | | | | | | | | | | | | | | | Macro CONFIG_FSL_SATA_V2 is defined if the SOC has a V2 Freescale SATA controller, so it should be defined in config_mpc85xx.h instead of the various board header files. So now CONFIG_FSL_SATA_V2 is always defined on the P1013, P1022, P2041, P3041, P5010, and P5020. It was already defined for the P1010 and P1014.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Erratum A-003474: Internal DDR calibration circuit is not supported Impact: Experience shows no significant benefit to device operation with auto-calibration enabled versus it disabled. To ensure consistent timing results, Freescale recommends this feature be disabled in future customer products. There should be no impact to parts that are already operating in the field. Workaround: Prior to setting DDR_SDRAM_CFG[MEM_EN]=1, do the following: 1. Write a value of 0x0000_0015 to the register at offset CCSRBAR + DDR OFFSET + 0xf30 2. Write a value of 0x2400_0000 to the register at offset CCSRBAR + DDR OFFSET + 0xf54 Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Erratum A-003999: Running Floating Point instructions requires special initialization. Impact: Floating point arithmetic operations may result in an incorrect value. Workaround: Perform a read modify write to set bit 7 to a 1 in SPR 977 before executing any floating point arithmetic operation. This bit can be set when setting MSR[FP], and can be cleared when clearing MSR[FP]. Alternatively, the bit can be set once at boot time, and never cleared. There will be no performance degradation due to setting this bit. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* | powerpc/85xx: Add support for Book-E MMU Arch v2.0Kumar Gala2011-11-08-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | A few of the config registers changed definition between MMU v1.0 and MMUv2.0. The new e6500 core from Freescale implements v2.0 of the architecture. Specifically, how we determine the size of TLB entries we support in the variable size (or TLBCAM/TLB1) array is specified in a new register (TLBnPS - TLB n Page size) instead of via TLBnCFG.

| | | | | | | | | | | | | | | | | | | | | | | | Fix USB device-fixup warning "node not found". This was occuring because of static nature of start_offset variable Static start_offset was storing offset of last node modified, and was becoming issue if node fixup is carried multiple times, resulting in "node not found" warning Signed-off-by: Ramneek Mehresh <ramneek.mehresh@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* | powerpc/85xx: resize the boot page TLB before relocating CCSRTimur Tabi2011-11-08-0/+49
| | | | | | | | | | | | | | | | | | | | On some Freescale systems (e.g. those booted from the on-chip ROM), the TLB that covers the boot page can also cover CCSR, which breaks the CCSR relocation code. To fix this, we resize the boot page TLB so that it only covers the 4KB boot page. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* | powerpc/85xx: verify the current address of CCSR before relocating itTimur Tabi2011-11-08-0/+27
| | | | | | | | | | | | | | | | | | | | | | Verify that CCSR is actually located where it is supposed to be before we relocate it. This is useful in detecting U-Boot configurations that are broken (e.g. an incorrect value for CONFIG_SYS_CCSRBAR_DEFAULT). If the current value is wrong, we enter an infinite loop, which is handy for debuggers. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* | powerpc/85xx: fix definition of MAS register macrosTimur Tabi2011-11-08-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Some of the MAS register macros do not protect the parameter with parentheses, which could cause wrong values if the parameter includes operators. Also fix the definition of TSIZE_TO_BYTES() so that it actually uses the parameter. This hasn't caused any problems to date because the parameter was always been 'tsize'.
