In fact, there is only one +bank of flash, which is divided into low and high half. Each is controlled by +the most significant bit of the address bus. The so called "bank" is only for +convenience. + +There is a switch which allows the "bank" to be selected. The switch +settings for updating flash are given below. + +The u-boot commands for copying the boot-bank into the secondary bank are +as follows: + + erase ff800000 ff880000 + cp.b ff000000 ff800000 80000 + +U-boot commands for downloading an image via tftp and flashing +it into the secondary bank: + + tftp 10000 + erase ff000000 ff080000 + cp.b 10000 ff000000 80000 + + +After copying the image into the second bank of flash, be sure to toggle +SW3[4] on board before resetting the board in order to set the +secondary bank as the boot-bank. + + +Board Switches +---------------------- + + +Most switches on the board should not be changed.

Add 7447A and 7448 processor support. 2. Add the following flags. CFG_CONFIG_BUS_CLK : If the 74xx bus frequency can be configured dynamically (such as by switch on board), this flag should be set. CFG_EXCEPTION_AFTER_RELOCATE: If an exception occurs after the u-boot relocates to RAM, this flag should be set. CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the system hang in exception, this flag should be set. There is a design issue for tsi108/109 pci configure read. When pci scan the slots, if there is no pci card, the tsi108/9 will cause a machine check exception for mpc7448 processor.

08/21] Tundra tsi108 on chip Ethernet controller support. The following is a brief description of the Ethernet controller: The Tsi108/9 Ethernet Controller connects Switch Fabric to two independent Gigabit Ethernet ports,E0 and E1. It uses a single Management interface to manage the two physical connection devices (PHYs). Each Ethernet port has its own statistics monitor that tracks and reports key interface statistics. Each port supports a 256-entry hash table for address filtering. In addition, each port is bridged to the Switch Fabric through a 2-Kbyte transmit FIFO and a 4-Kbyte Receive FIFO. Each Ethernet port also has a pair of internal Ethernet DMA channels to support the transmit and receive data flows. The Ethernet DMA channels use descriptors set up in memory, the memory map of the device, and access via the Switch Fabric. The Ethernet Controller?s DMA arbiter handles arbitration for the Switch Fabric. The Controller also has a register businterface for register accesses and status monitor control. The PMD (Physical Media Device) interface operates in MII, GMII, or TBI modes. The MII mode is used for connecting with 10 or 100 Mbit/s PMDs. The GMII and TBI modes are used to connect with Gigabit PMDs. Internal data flows to and from the Ethernet Controller through the Switch Fabric. Each Ethernet port uses its transmit and receive DMA channels to manage data flows through buffer descriptors that are predefined by the system (the descriptors can exist anywhere in the system memory map). These descriptors are data structures that point to buffers filled with data ready to transmit over Ethernet, or they point to empty buffers ready to receive data from Ethernet.

Subject: [PATCH 15/21] Fix the exception occuring in RAM table search issue. The original search_one_table() function code can only processes the search for the exception occurring in FLASH/ROM, because the exception and fixup table usually locate in FLASH. If the exception address is also in FLASH, it will be OK. If the exception occurs in RAM, after the u-boot relocation, a relocation offset should be added. clean up the code in cpu/74xx_7xx/cpu.c Signed-off-by: Roy Zang --- cpu/74xx_7xx/cpu.c | 16 ++++++---------- include/configs/mpc7448hpc2.h | 1 - lib_ppc/extable.c | 27 +++++++++++++++++---------- 3 files changed, 23 insertions(+), 21 deletions(-) diff --git a/cpu/74xx_7xx/cpu.c b/cpu/74xx_7xx/cpu.c index ca45ca045..84d5da311 100644 --- a/cpu/74xx_7xx/cpu.c +++ b/cpu/74xx_7xx/cpu.c @@ -108,11 +108,11 @@ get_cpu_type(void) case 0x8003: type = CPU_7447A; break; - + case 0x8004: type = CPU_7448; break; - + default: break; } @@ -164,6 +164,10 @@ int checkcpu (void) str = "MPC7410"; break; + case CPU_7447A: + str = "MPC7447A"; + break; + case CPU_7448: str = "MPC7448"; break; @@ -180,14 +184,6 @@ int checkcpu (void) str = "MPC7457"; break; - case CPU_7447A: - str = "MPC7447A"; - break; - - case CPU_7448: - str = "MPC7448"; - break; - default: printf("Unknown CPU -- PVR: 0x%08x\n", pvr); return -1; diff --git a/include/configs/mpc7448hpc2.h b/include/configs/mpc7448hpc2.h index b13b699b5..c9131a432 100644 --- a/include/configs/mpc7448hpc2.h +++ b/include/configs/mpc7448hpc2.h @@ -439,6 +439,5 @@ */ #define BOOTFLAG_COLD 0x01 /* Normal Power-On: Boot from FLASH */ #define BOOTFLAG_WARM 0x02 /* Software reboot */ -#define CFG_EXCEPTION_AFTER_RELOCATE #define CFG_SERIAL_HANG_IN_EXCEPTION #endif /* __CONFIG_H */ diff --git a/lib_ppc/extable.c b/lib_ppc/extable.c index 34b5d460c..623b5f129 100644 --- a/lib_ppc/extable.c +++ b/lib_ppc/extable.c @@ -57,16 +57,22 @@ search_one_table(const struct exception_table_entry *first, long diff; mid = (last - first) / 2 + first; -#ifdef CFG_EXCEPTION_AFTER_RELOCATE - diff = (mid->insn + gd->reloc_off) - value; - if (diff == 0) - return (mid->fixup + gd->reloc_off); -#else - diff = mid->insn - value; - if (diff == 0) - return mid->fixup; -#endif - else if (diff < 0) + if (mid > CFG_MONITOR_BASE){ + /* exception occurs in FLASH, before u-boot relocation. + * No relocation offset is needed. + */ + diff = mid->insn - value; + if (diff == 0) + return mid->fixup; + } else { + /* exception occurs in RAM, after u-boot relocation. + * A relocation offset should be added. + */ + diff = (mid->insn + gd->reloc_off) - value; + if (diff == 0) + return (mid->fixup + gd->reloc_off); + } + if (diff < 0) first = mid+1; else last = mid-1; @@ -83,6 +89,7 @@ search_exception_table(unsigned long addr) /* There is only the kernel to search. */ ret = search_one_table(__start___ex_table, __stop___ex_table-1, addr); + /* if the serial port does not hang in exception, printf can be used */ #if !defined(CFG_SERIAL_HANG_IN_EXCEPTION) if (ex_tab_message) printf("Bus Fault @ 0x%08lx, fixup 0x%08lx\n", addr, ret); From 6f12c61cf31ed73d72ddfcfc712a854a3a177aaf Mon Sep 17 00:00:00 2001 From: roy zang Date: Mon, 4 Dec 2006 14:33:08 +0800 Subject: [PATCH 16/21] Remove the duplicate memory test code for mpc744ihpc2 board.
