Redundant Environment: protect full sector size

2009-06-03T22:16:16Z

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.

Fix all linker script to handle all rodata sections

2009-03-20T21:39:12Z

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

boards: get mac address from env and move load_sernum_ethaddr() to board init

2009-03-20T21:39:12Z

The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. Rather than have common ppc code call a board-specific function like load_sernum_ethaddr(), have each board call it in its own board-specific misc_init_r() function. The boards that get converted here are: - kup4k/kup4x - pcs440ep - tqm8xx Signed-off-by: Mike Frysinger CC: Ben Warren CC: Stefan Roese

TQM8xxL: make some room in low memory for future needs

2009-02-19T13:01:42Z

THe TQM8xxL use a ahnd-optimized linker script to efficiently use the small boot sectors in the flash. This patch makes some room in the first sector to prepare for a size increase of lib_generic/vsprintf.o by a future patch. Signed-off-by: Wolfgang Denk

TQM85xx: Fix a couple warnings in TQM8548 build

2009-02-17T00:06:03Z

The ecm variable in sdram.c was being declared for all 8548, but only used by specific 8548 boards, so we make that variable require those specific boards, too The nand code was using an index "i" into a table, and then re-using "i" to set addresses for each upm. However, then it relied on the old value of i still being there to enable things. Changed the second "i" to "j" Signed-off-by: Andy Fleming

MPC85xx: TQM8548: workaround for erratum DDR 19 and 20

2009-02-17T00:06:02Z

This patch adds the workaround for erratum DDR20 according to MPC8548 Device Errata document, Rev. 1: "CKE signal may not function correctly after assertion of HRESET". Furthermore, the bug DDR19 is fixed in processor version 2.1 and the work-around must be removed. Signed-off-by: Wolfgang Grandegger

MPC85xx: TQM8548: use cache for AG and BE variants

2009-02-17T00:06:02Z

This patch makes accesses to the system memory cachable by removing the caching-inhibited and guarded flags from the relevant TLB entries for the TQM8548_BE and TQM8548_AG modules. FYI, the Freescale MPC85* boards are configured similarly. This results in a big averall performace improvement. TFTP downloads, NAND Flash accesses, kernel boots, etc. are much faster.
