2013-10-31powerpc: convert makefiles to Kbuild styleMasahiro Yamada
Note: arch/powerpc/cpu/mpc8260/Makefile is originally like follows: ---<snip>--- START = start.o kgdb.o COBJS = traps.o serial_smc.o serial_scc.o cpu.o cpu_init.o speed.o \ ---<snip>--- COBJS-$(CONFIG_ETHER_ON_SCC) = ether_scc.o ---<snip>--- $(LIB): $(OBJS) $(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o) The link rule `$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)' is weird. kbdg.o is not included in $(OBJS) but linked into $(LIB) and $(LIB) is not dependent on kgdb.o. (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.

2013-10-24mpc8xxx: set x2 DDR3 refresh rate if SPD config requires itValentin Longchamp
If the DDR3 module supports industrial temperature range and requires the x2 refresh rate for that temp range, the refresh period must be 3.9us instead of 7.8 us. This was successfuly tested on kmp204x board with some MT41K128M16 DDR3 RAM chips (no module used, chips directly soldered on board with an SPD EEPROM).

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.

2013-08-09powerpc/mpc8xxx: Set inactive csn_bnds to 0xffffffffYork Sun
When chip select interleaving is enabled, cs0_bnds is used for address binding. Other csn_bnds are not used. When two controllers interleaving is enabled, cs0_bnds of both controllers are used, other csn_bnds are not. However, the unused csn_bnds may be used internally for calculating addresses for calibration. Setting those registers to 0 may confuse controllers in some cases. Instead, setting them to 0xffffffff together with normal LAWs will guarantee the address is not mapped to DDR. Signed-off-by: York Sun <yorksun@freescale.com>

2013-06-20powerpc/boot: Change the macro of Boot from SRIO and PCIE master moduleLiu Gang
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.

The BSC9132 is a highly integrated device that targets the evolving Microcell, Picocell, and Enterprise-Femto base station market subsegments. 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.

2013-01-30powerpc/mpc8xxx: Enable entering DDR debugging by key pressYork Sun
Using environmental variable "ddr_interactive" to activate interactive DDR debugging seomtiems is not enough. For example, after updating SPD with a valid but wrong image, u-boot won't come up due to wrong DDR configuration. By enabling key press method, we can enter debug mode to have a chance to boot without using other tools to recover the board. CONFIG_FSL_DDR_INTERACTIVE needs to be defined in header file. To enter the debug mode by key press, press key 'd' shortly after reset, like one would do to abort auto booting. It is fixed to lower case 'd' at this moment.

2012-11-278xxx: Change all 8*xx_DDR addresses to 8xxxAndy Fleming
There were a number of shared files that were using CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and several variants (DDR2, DDR3). A recent patchset added 85xx-specific ones to code which was used by 86xx systems. After reviewing places where these constants were used, and noting that the type definitions of the pointers assigned to point to those addresses were the same, the cleanest approach to fixing this problem was to unify the namespace for the 85xx, 83xx, and 86xx DDR address definitions. This patch does: s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g All 85xx, 86xx, and 83xx have been built with this change.

Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL and CONFIG_SPL_BUILD, respectively. CONFIG_NAND_SPL can be removed once the last mpc85xx nand_spl target is gone. CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't seem right to overload it for meaning SPL as well as nand_spl does. Even if it's somewhat appropriate for the main u-boot, the SPL itself isn't (necessarily) ramboot, and we don't have separate configs for SPL and main u-boot. It was also inconsistent, as other platforms such as mpc83xx didn't use CONFIG_RAMBOOT in this way. Signed-off-by: Scott Wood <scottwood@freescale.com> Cc: Andy Fleming <afleming@freescale.com>

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.

It is possible that the pre- translation address selects one DDR controller but the post-translation address exists in a different DDR controller when using certain DDR controller interleaving modes. The device may fail to boot under these circumstances.

Starting from DDRC 4.7, the decoding of ODT for IOs is 000 -> Termsel off 001 -> 120 Ohm 010 -> 180 Ohm 011 -> 75 Ohm 100 -> 110 Ohm 101 -> 60 Ohm 110 -> 70 Ohm 111 -> 47 Ohm Add two write leveling registers. Each QDS now has its own write leveling start value. In case of zero value, the value of QDS0 will be used. These values are board-specific and are set in board files.
