2017-04-13board_f: Rename initdram() to dram_init()Simon Glass
This allows us to use the same DRAM init function on all archs. Add a dummy function for arc, which does not use DRAM init here. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: Dummy function on nios2] Signed-off-by: Tom Rini <trini@konsulko.com>
2017-04-05board_f: Drop return value from initdram()Simon Glass
At present we cannot use this function as an init sequence call without a wrapper, since it returns the RAM size. Adjust it to set the RAM size in global_data instead, and return 0 on success. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Stefan Roese <sr@denx.de>
2017-04-05board_f: Drop board_type parameter from initdram()Simon Glass
It looks like only cm5200 and tqm8xx use this feature, so we don't really need it in generic code. Drop it and have the users access gd->board_type directly. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Stefan Roese <sr@denx.de>

2011-11-03mpc83xx: Rename CONFIG_SYS_DDR_CONFIG and cleanup DDR csbnds codeJoe Hershberger
Rename CONFIG_SYS_DDR_CONFIG to include which CS it is configuring Cleanup the setting of the csnbds to respect the setting of CONFIG_SYS_DDR_SDRAM_BASE Use __ilog2 instead of writing the code to compute it Disable unused CS configs Ensure ddrlaw.bar is configured Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Cc: Joe Hershberger <joe.hershberger@gmail.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
2010-07-1683xx/85xx/86xx: LBC register cleanupBecky Bruce
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.

2009-12-05Generic udelay() with watchdog supportIngo van Lil
According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>
2008-10-29Make Freescale local bus registers available for both 83xx and 85xx.Haiying Wang
- Rename lbus83xx_t to fsl_lbus_t and move it to asm/fsl_lbc.h so that it can be shared by both 83xx and 85xx - Remove lbus83xx_t and replace it with fsl_lbus_t in all 83xx boards files which use lbus83xx_t. - Move FMR, FIR, FCR, FPAR, LTESR from mpc83xx.h to asm/fsl_lbc.h so that 85xx can share them.

2008-09-24mpc83xx: spd_sdram: fix ddr sdram base address assignment bugAnton Vorontsov
The spd_dram code shifts the base address, then masks 20 bits, but forgets to shift the base address back. Fix this by just masking the base address correctly. Found this bug while trying to relocate a DDR memory at the base != 0. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
2008-08-12NAND boot: MPC8313ERDB supportScott Wood
Note that with older board revisions, NAND boot may only work after a power-on reset, and not after a warm reset. I don't have a newer board to test on; if you have a board with a 33MHz crystal, please let me know if it works after a warm reset. Signed-off-by: Scott Wood <scottwood@freescale.com>
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>
