2013-11-25Driver/DDR: Moving Freescale DDR driver to a common driverYork Sun
Freescale DDR driver has been used for mpc83xx, mpc85xx, mpc86xx SoCs. The similar DDR controllers will be used for ARM-based SoCs. Signed-off-by: York Sun <yorksun@freescale.com>
2013-11-13powerpc/85xx: fix broken cpu "clock-frequency" propertyLaurentiu TUDOR
When indexing freqProcessor[] we use the first value in the cpu's "reg" property, which on new e6500 cores IDs the threads. But freqProcessor[] should be indexed with a core index so, when fixing "the clock-frequency" cpu node property, access the freqProcessor[] with the core index derived from the "reg' property. If we don't do this, last half of the "cpu" nodes will have broken "clock-frequency" values. Signed-off-by: Laurentiu Tudor <Laurentiu.Tudor@freescale.com> Cc: York Sun <yorksun@freescale.com>
2013-11-13powerpc/t4240: fix per pci endpoint liodn offsetsLaurentiu TUDOR
Update the code that builds the pci endpoint liodn offset list so that it doesn't overlap with other liodns and doesn't generate negative offsets like: fsl,liodn-offset-list = <0 0xffffffcd 0xffffffcf 0xffffffd1 0xffffffd3 0xffffffd5 0xffffffd7 0xffffffd9 0xffffffdb>; The update consists in adding a parameter to the function that builds the list to specify the base liodn. On PCI v2.4 use the old base = 256 and, on PCI 3.0 where some of the PCIE liodns are larger than 256, use a base = 1024. The version check is based on the PCI controller's version register.

(Broken dependency tracking) So, START = start.o kgdb.o shoud have been START = start.o SOBJS = kgdb.o That is why this commit adds kgdb.o to obj-y, not to extra-y.

2013-08-20powerpc: mpc85xx: Support booting from SD Card with SPLYing Zhang
The code from the internal on-chip ROM. It loads the final uboot image into DDR, then jump to it to begin execution. The SPL's size is sizeable, the maximum size must not exceed the size of L2 SRAM. It initializes the DDR through SPD code, and copys final uboot image to DDR. So there are two stage uboot images: * spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that ddr spd code can get the interleaving mode setting in env. It loads final uboot image from offset 96KB. * final uboot image, size is variable depends on the functions enabled.

2013-08-20fsl_i2c: add workaround for the erratum I2C A004447Chunhe Lan
This workaround is for the erratum I2C A004447. Device reference manual provides a scheme that allows the I2C master controller to generate nine SCL pulses, which enable an I2C slave device that held SDA low to release SDA. However, due to this erratum, this scheme no longer works. In addition, when I2C is used as a source of the PBL, the state machine is not able to recover. At the same time, delete the reduplicative definition of SVR_VER and SVR_REV. The SVR_REV is the low 8 bits rather than the low 16 bits of svr. And we use the CONFIG_SYS_FSL_A004447_SVR_REV macro instead of hard-code value 0x10, 0x11 and 0x20. The CONFIG_SYS_FSL_A004447_SVR_REV = 0x00 represents that one version of platform has this I2C errata. So enable this errata by IS_SVR_REV(svr, maj, min) function.

2013-08-09powerpc/srio-pcie-boot: Avoid the NOR_BOOT macro when boot from SRIO/PCIELiu Gang
When a board (slave) boots from SRIO/PCIE, it would get the instructions from a remote board (master) by SRIO/PCIE interface, and the slave's u-boot image should be built with the SYS_TEXT_BASE=0xFFF80000; So the u-boot of the slave should avoid the NOR_BOOT branch at the booting stage. For example, when a P2041RDB boots from SRIO/PCIE, it will set TLB entry 15 from base address "CONFIG_SYS_MONITOR_BASE & 0xffc00000", and with the 4M size as the boot window in NOR_BOOT branch. Because the CONFIG_SYS_MONITOR_BASE = CONFIG_SYS_TEXT_BASE = 0xFFF80000, so the TLB entry will be from base address 0xffc00000 and with 4M size. Then the u-boot will set TLB entry 14 from base address "CONFIG_SYS_INIT_RAM_ADDR", and with the 16K size as the initial stack window. For the P2041RDB platform, the CONFIG_SYS_INIT_RAM_ADDR = 0xffd00000. So the TLB entry 14 and 15 will be in confliction. There will be right TLB entries configurations when avoid the NOR_BOOT branch and set the boot window from 0xfff00000 with 1M size space. Signed-off-by: Liu Gang <Gang.Liu@freescale.com>
