Please make sure to configure jumper J7 to position 2-3 when booting from NOR, and to position 1-2 when booting for NAND. I also added a board command to configure the I2C bootstrap EEPROM values. Right now only 267MHz is support for booting either via NOR or NAND FLASH. Here the usage: => bootstrap 267 nor ;to configure the board for 267MHz NOR booting => bootstrap 267 nand ;to configure the board for 267MHz NNAND booting Signed-off-by: Stefan Roese --- MAKEALL | 33 +++--- Makefile | 9 ++ board/amcc/acadia/Makefile | 2 +- board/amcc/acadia/acadia.c | 10 +- board/amcc/acadia/cmd_acadia.c | 101 +++++++++++++++++ board/amcc/acadia/config.mk | 6 + board/amcc/acadia/memory.c | 11 +- board/amcc/acadia/u-boot-nand.lds | 137 +++++++++++++++++++++++ cpu/ppc4xx/start.S | 72 +++++++++--- include/configs/acadia.h | 152 ++++++++++++++++++++------ include/ppc405.h | 8 ++ nand_spl/board/amcc/acadia/Makefile | 104 ++++++++++++++++++ nand_spl/board/amcc/acadia/config.mk | 47 ++++++++ nand_spl/board/amcc/acadia/u-boot.lds | 63 +++++++++++ 14 files changed, 685 insertions(+), 70 deletions(-) create mode 100644 board/amcc/acadia/cmd_acadia.c create mode 100644 board/amcc/acadia/u-boot-nand.lds create mode 100644 nand_spl/board/amcc/acadia/Makefile create mode 100644 nand_spl/board/amcc/acadia/config.mk create mode 100644 nand_spl/board/amcc/acadia/u-boot.lds diff --git a/MAKEALL b/MAKEALL index 81f5dfcb05..67d39a716f 100755 --- a/MAKEALL +++ b/MAKEALL @@ -75,22 +75,23 @@ LIST_8xx=" \ ######################################################################### LIST_4xx=" \ - acadia ADCIOP alpr AP1000 \ - AR405 ASH405 bamboo bamboo_nand \ - bubinga CANBT CMS700 CPCI2DP \ - CPCI405 CPCI4052 CPCI405AB CPCI405DT \ - CPCI440 CPCIISER4 CRAYL1 csb272 \ - csb472 DASA_SIM DP405 DU405 \ - ebony ERIC EXBITGEN G2000 \ - HH405 HUB405 JSE KAREF \ - katmai luan METROBOX MIP405 \ - MIP405T ML2 ml300 ocotea \ - OCRTC ORSG p3p440 PCI405 \ - pcs440ep PIP405 PLU405 PMC405 \ - PPChameleonEVB sbc405 sc3 sequoia \ - sequoia_nand taishan VOH405 VOM405 \ - W7OLMC W7OLMG walnut WUH405 \ - XPEDITE1K yellowstone yosemite yucca \ + acadia acadia_nand ADCIOP alpr \ + AP1000 AR405 ASH405 bamboo \ + bamboo_nand bubinga CANBT CMS700 \ + CPCI2DP CPCI405 CPCI4052 CPCI405AB \ + CPCI405DT CPCI440 CPCIISER4 CRAYL1 \ + csb272 csb472 DASA_SIM DP405 \ + DU405 ebony ERIC EXBITGEN \ + G2000 HH405 HUB405 JSE \ + KAREF katmai luan METROBOX \ + MIP405 MIP405T ML2 ml300 \ + ocotea OCRTC ORSG p3p440 \ + PCI405 pcs440ep PIP405 PLU405 \ + PMC405 PPChameleonEVB sbc405 sc3 \ + sequoia sequoia_nand taishan VOH405 \ + VOM405 W7OLMC W7OLMG walnut \ + WUH405 XPEDITE1K yellowstone yosemite \ + yucca \ " ######################################################################### diff --git a/Makefile b/Makefile index 463757c43b..6b70dd53b2 100644 --- a/Makefile +++ b/Makefile @@ -1017,6 +1017,15 @@ xtract_4xx = $(subst _25,,$(subst _33,,$(subst _BA,,$(subst _ME,,$(subst _HI,,$( acadia_config: unconfig @$(MKCONFIG) $(@:_config=) ppc ppc4xx acadia amcc +acadia_nand_config: unconfig + @mkdir -p $(obj)include + @mkdir -p $(obj)nand_spl + @mkdir -p $(obj)board/amcc/acadia + @echo "#define CONFIG_NAND_U_BOOT" > $(obj)include/config.h + @$(MKCONFIG) -n $@ -a acadia ppc ppc4xx acadia amcc + @echo "TEXT_BASE = 0x01000000" > $(obj)board/amcc/acadia/config.tmp + @echo "CONFIG_NAND_U_BOOT = y" >> $(obj)include/config.mk + ADCIOP_config: unconfig @$(MKCONFIG) $(@:_config=) ppc ppc4xx adciop esd diff --git a/board/amcc/acadia/Makefile b/board/amcc/acadia/Makefile index abcbf3e439..ddbcb8091f 100644 --- a/board/amcc/acadia/Makefile +++ b/board/amcc/acadia/Makefile @@ -25,7 +25,7 @@ include $(TOPDIR)/config.mk LIB = $(obj)lib$(BOARD).a -COBJS = $(BOARD).o cpr.o memory.o +COBJS = $(BOARD).o cmd_acadia.o cpr.o memory.o SOBJS = SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) diff --git a/board/amcc/acadia/acadia.c b/board/amcc/acadia/acadia.c index 3b63c8a741..46d63e6308 100644 --- a/board/amcc/acadia/acadia.c +++ b/board/amcc/acadia/acadia.c @@ -63,8 +63,14 @@ int board_early_init_f(void) acadia_gpio_init();
