* 83xx/85xx/86xx: LBC register cleanupBecky Bruce2010-07-16-2/+0
| | | | | | | | | | | | | | | | | | | | | 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.

* 83xx/85xx: further localbus cleanupsAnton Vorontsov2008-06-10-35/+0
| | | | | | | | | | | | | move the BRx_* and ORx_* left behind in mpc85xx.h The same is needed for mpc8xx.h and mpc8260.h (defines are almost the same, just few differences which needs some attention though). But the bad news for mpc8xx and mpc8260 is that there are a lot of users of these defines. So this cleanup I'll leave for the "better times".

* 83xx/85xx/86xx: factor out Freescale Localbus defines out of mpc83xx.hAnton Vorontsov2008-06-10-0/+2
| | | | | | | | | This patch moves Freescale Localbus defines out of mpc83xx.h, so we could use it on MPC85xx and MPC86xx processors. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Acked-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
* 85xx start.S cleanup and exception supportAndy Fleming2007-08-14-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | From: Ed Swarthout <Ed.Swarthout@freescale.com> Support external interrupts from platform to eliminate system hangs. Define CONFIG_INTERRUPTS board configure option to enable. Enable ecm, ddr, lbc, and pci/pcie error interrupts in PIC. Remove extra cpu initialization redundant with hardware initialization. Whitespace cleanup. Define and use _START_OFFSET consistent with other processors using ppc_asm.tmpl Move additional code from .text to boot page to make room for exception vectors at start of image. Handle Machine Check, External and Critical exceptions. Fix e500 machine check error determination in traps.c TEXT_BASE can now be 0xfffc_0000 - which cuts binary image in half.
