* ppc: Don't initialize write protected NOR flashesJohn Schmoller2010-10-20-1/+15
| | | | | | | | | | | | If a NOR flash is write protected it can not be initialized/detected so add the ability for boards to skip NOR initialization on bootup. A board can skip NOR initialization by implementing the board_flash_wp_on() function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 0ad7f0950a9bc0a69b3cd5f34ccf7da25fcf1c6d [ppc4xx: cleanup default environment for AMCC boards] broke the default env for many PPC4xx boards.

* | 85xx: Add support for not releasing secondary cores via 'mp_holdoff'Aaron Sierra2010-10-20-3/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | Some OSes require that secondary cores not be initialized when they are booted (eg VxWorks). By default when U-Boot is compiled with the CONFIG_MP option all secondary cores are brought out of reset and held in spinloops. Setting the "mp_holdoff" environment variable to 'yes' or '1' will cause U-Boot to leave secondary cores in their default state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The memory test is performed after DDR initialization when U-boot stills runs in flash and cache. On recent mpc85xx platforms, the total memory can be more than 2GB. To cover whole memory, it needs be mapped 2GB at a time using a sliding TLB window. After the testing, DDR is remapped with up to 2GB memory from the lowest address as normal. If memory test fails, DDR DIMM SPD and DDR controller registers are dumped for further debugging.

* | always relocate fdt into an lmb-allocated memory blockTimur Tabi2010-10-20-55/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device tree (fdt) must always exist in within the bootmap (usually the first 16MB of RAM). If it doesn't, then boot_relocate_fdt() will allocate an LMB region in the bootmap and copy the fdt into that region. It will also increase the size of the fdt. If the fdt is already in the bootmap, then previously the memory was just reserved. There was no contingency if the reservation failed, however. By always allocating an lmb region and copying/resizing the fdt into that region, the code is simplified and the memory region is always allocated properly. Also change the types of some variables to avoid some typecasts.

* FAT: buffer overflow with FAT12/16Stefano Babic2010-10-20-1/+1
| | | | | | | | | | | | | Last commit 3831530dcb7b71329c272ccd6181f8038b6a6dd0a was intended "explicitly specify FAT12/16 root directory parsing buffer size, instead of relying on cluster size". Howver, the underlying function requires the size of the buffer in blocks, not in bytes, and instead of passing a double sector size a request for 1024 blocks is sent. This generates a buffer overflow with overwriting of other structure (in the case seen, USB structures were overwritten).

* USB: sync Queue Element Transfer Descriptor against EHCI specWolfgang Denk2010-10-20-5/+10
| | | | | | | | | | | | | | | | | | | Appendix B "EHCI 64-Bit Data Structures" of the "Enhanced Host Controller Interface Specification for Universal Serial Bus" (Rev. 1.0, March 12, 2002) defines additional fields which were missing in U-Boot's struct qTD; as these are also present in recent versions of struct ehci_qtd in the Linux kernel, we add them here, too. This fixes some nasty memory corruption problems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Firstly, this fixes relocation issues. I had to use part of Dcache as RAM for a while. I also moved around the lowlevel init code. It turned out so most of the lowlevel init code ended in cpu.c (and eventually was rewritten into C). This will also allow easier operation with FDT, multi-CPU-model support etc. in later releases.
