* tqm85xx: Remove board_add_ram_info()Peter Tyser2009-07-22-30/+3
| | | | | | | | This is in preparation for adding one common 8xxx board_add_ram_info() function for all 8xxx boards Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* TQM85xx: Fix a couple warnings in TQM8548 buildAndy Fleming2009-02-16-0/+2
| | | | | | | | | | | | 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 <afleming@freescale.com>
* MPC85xx: TQM8548: workaround for erratum DDR 19 and 20Wolfgang Grandegger2009-02-16-8/+108
| | | | | | | | | 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 <wg@grandegger.com>

* MPC85xx: TQM8548: fix SDRAM timing for 533 MHzWolfgang Grandegger2009-02-16-6/+8
| | | | | | | | | | According to new TQM8548 timing specification: Refresh Recovery: 34 -> 53 clocks CKE pulse width: 1 -> 3 cycles Window for four activities: 13 -> 14 cycles Signed-off-by: Jens Gehrlein <sew_s@tqs.de> Signed-off-by: Wolfgang Grandegger <wg@grandegger.com>

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | 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>
* TQM8548: Basic support for the TQM8548 modulesWolfgang Grandegger2008-06-11-2/+148
| | | | | | | | | | | | This patch adds basic support for the TQM8548 module from TQ-Components (http://www.tqc.de/) including DDR2 SDRAM initialisation and support for eTSEC 3 and 4 Furthermore Flash buffer write has been enabled to speed up output to the Flash by approx. a factor of 10.
