2009-06-03Redundant Environment: protect full sector sizeWolfgang Denk
Several boards used different ways to specify the size of the protected area when enabling flash write protection for the sectors holding the environment variables: some used CONFIG_ENV_SIZE and CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even a mix of both for the "normal" and the "redundant" areas. Normally, this makes no difference at all. However, things are different when you have to deal with boards that can come with different types of flash chips, which may have different sector sizes. Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the biggest sector size, which may include several sectors on boards using the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the case that only the first of these sectors get protected, while the following ones aren't. This is no real problem, but it can be confusing for the user - especially on boards that use CONFIG_ENV_SECT_SIZE to protect the "normal" areas, while using CONFIG_ENV_SIZE_REDUND for the "redundant" area. To avoid such inconsistencies, I changed all sucn boards that I found to consistently use CONFIG_ENV_SECT_SIZE for protection. This should not cause any functional changes to the code.

2009-03-20Fix all linker script to handle all rodata sectionsTrent Piepho
A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2008-12-20mpc8xxx: LCRR[CLKDIV] is sometimes five bitsTrent Piepho
On newer CPUs, 8536, 8572, and 8610, the CLKDIV field of LCRR is five bits instead of four. In order to avoid an ifdef, LCRR_CLKDIV is set to 0x1f on all systems. It should be safe as the fifth bit was defined as reserved and set to 0. Code that was using a hard coded 0x0f is changed to use LCRR_CLKDIV.

since commit be0bd8234b9777ecd63c4c686f72af070d886517 tlb entry for socrates DDR SDRAM will be reconfigured by setup_ddr_tlbs() from initdram() causing an inconsistency with previously configured DDR SDRAM tlb entry from tlb_table: socrates>l2cam 7 9 IDX PID EPN SIZE V TS RPN U0-U3 WIMGE UUUSSS 7 : 00 00000000 256MB V 0 -> 0_00000000 0000 -I-G- ---RWX 8 : 00 00000000 256MB V 0 -> 0_00000000 0000 ----- ---RWX 9 : 00 10000000 256MB V 0 -> 0_10000000 0000 ----- ---RWX This patch makes the presence of the DDR SDRAM tlb entry in the tlb_table dependent on CONFIG_SPD_EEPROM to avoid this inconsistency.

2008-10-18Pass dimm parameters to populate populate controller optionsHaiying Wang
Because some dimm parameters like n_ranks needs to be used with the board frequency to choose the board parameters like clk_adjust etc. in the board_specific_paramesters table of the board ddr file, we need to pass the dimm parameters to the board file. * move ddr dimm parameters header file from /cpu to /include directory. * add ddr dimm parameters to populate board specific options. * Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.

Currently U-Boot crashes after relocation to RAM. Changing the CPO value of the DDR SDRAM TIMING_CFG_2 register to READ_LAT + 1 (to the value it was before conversion of socrates to new DDR code) fixes the problem. Signed-off-by: Anatolij Gustschin <agust@denx.de>

2008-09-0985xx: Socrates: Major code update.Detlev Zundel
- Update the local bus ranges in the FDT for Linux for the various devices connected to the local bus via chip-select. - Set the LCRR_DBYP bit in the LCRR for local bus frequencies lower than 66 MHz and uses I/O accessor functions consequently. - UPM data update. - Update of default environment and configuration. Use I2C multibus as we do have two I2C buses. Also enable sdram and ext2 commands.

2008-06-12Change initdram() return type to phys_size_tBecky Bruce
This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
