Switch from archive libraries to partial linking Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

powerpc/85xx: Add support for Integrated Flash Controller (IFC) The Integrated Flash Controller (IFC) is used to access the external NAND Flash, NOR Flash, EPROM, SRAM and Generic ASIC memories.Four chip selects are provided in IFC so that maximum of four Flash devices can be hooked, but only one can be accessed at a given time. Features supported by IFC are, - Functional muxing of pins between NAND, NOR and GPCM - Support memory banks of size 64KByte to 4 GBytes - Write protection capability (only for NAND and NOR) - Provision of Software Reset - Flexible Timing programmability for every chip select - NAND Machine - x8/ x16 NAND Flash Interface - SLC and MLC NAND Flash devices support with configurable page sizes of upto 4KB - Internal SRAM of 9KB which is directly mapped and availble at boot time for NAND Boot - Configurable block size - Boot chip select (CS0) available at system reset - NOR Machine - Data bus width of 8/16/32 - Compatible with asynchronous NOR Flash - Directly memory mapped - Supports address data multiplexed (ADM) NOR device - Boot chip select (CS0) available at system reset - GPCM Machine (NORMAL GPCM Mode) - Support for x8/16/32 bit device - Compatible with general purpose addressable device e.g. SRAM, ROM - External clock is supported with programmable division ratio - GPCM Machine (Generic ASIC Mode) - Support for x8/16/32 bit device - Address and Data are shared on I/O bus - Following Address and Data sequences can be supported on I/O bus - 32 bit I/O: AD - 16 bit I/O: AADD - 8 bit I/O : AAAADDDD - Configurable Even/Odd Parity on Address/Data bus supported Signed-off-by: Dipen Dudhat <Dipen.Dudhat@freescale.com> Acked-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

83xx/85xx/86xx: LBC register cleanup Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

powerpc/8xxx: Refactor SRIO initialization into common code Moved the SRIO init out of corenet_ds and into common code for 8xxx/QorIQ processors that have SRIO. We mimic what we do with PCIe controllers for SRIO. We utilize the fact that SRIO is over serdes to determine if its configured or not and thus can setup the LAWs needed for it dynamically. We additionally update the device tree (to remove the SRIO nodes) if the board doesn't have SRIO enabled. Introduced the following standard defines for board config.h: CONFIG_SYS_SRIO - Chip has SRIO or not CONFIG_SRIO1 - Board has SRIO 1 port available CONFIG_SRIO2 - Board has SRIO 2 port available (where 'n' is the port #) CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup) CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup) [ These mimic what we have for PCI and PCIe controllers ] Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Wolfgang Denk <wd@denx.de>

powerpc/mpc8xxx: move LAW code into arch/powerpc/cpu/mpc8xxx It's arch code and not a driver, so move it where it belongs. When it originally went into drivers/misc there was no 8xxx CPU directory. This will make new-SPL support a little easier since we can keep the CPU stuff together and not need to pull stuff in from drivers/misc.
