* ddr: altera: Rework initialize_tracking()Marek Vasut2015-08-08-53/+35
| | | | | | | | | | Clean the function up by getting rid of all the insane XOR-leftshift combos when assembling register values. While at it, remove all the ad-hoc variables necessary for this XOR-leftshift voodoo. Finally, get rid of the iterative division implementation of two constants and replace it with a DIV_ROUND_UP() macro :-) Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Fix ad-hoc iterative division implementationMarek Vasut2015-08-08-9/+2
| | | | | | | | Contemporary CPUs can perform division just fine, use this functionality and zap another implementation of iterative division :-) Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Minor clean up of set_jump_as_return()Marek Vasut2015-08-08-4/+8
| | | | | | Add kerneldoc and do a minor comment cleanup. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Factor out common codeMarek Vasut2015-08-08-99/+76
| | | | | | | | Factor out almost common code from rw_mgr_mem_handoff() and rw_mgr_mem_initialize() into separate rw_mgr_mem_load_user(). No functional change. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Factor out instruction loading from rw_mgr_mem_initialize()Marek Vasut2015-08-08-37/+37
| | | | | | Pull the duplicate code out into a separate function. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Clean up scc_mgr_apply_group_all_out_delay_add_all_ranks()Marek Vasut2015-08-08-9/+13
| | | | | | | Zap unused group_bgn parameter, fix and constify data types. Document in kerneldoc. No functional change. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Internal scc_mgr_apply_group_all_out_delay_add() cleanup part 2Marek Vasut2015-08-08-26/+24
| | | | | | | | | Clean the DQS and OCT parts of the function, clean up the chopped formatting strings in debug_cond() and slightly improve the code. Zap group_bgn argument as it is used only in debug messages. Document the function using kerneldoc. No functional change. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Internal scc_mgr_apply_group_all_out_delay_add() cleanup part 1Marek Vasut2015-08-08-35/+9
| | | | | | | | | | | | | | Apparently, in case of the DQ and DM, the value if the new_delay variable is calculated, but the value is not used. Zap the entire code which does calculate the value. It is not clear to me whether or not the code is doing the right thing in the first place. Right now, it calls scc_mgr_load_dq() and scc_mgr_load_dm() respectively, but I suspect it might need to call scc_mgr_apply_group_dq_out1_delay() and scc_mgr_apply_group_dm_out1_delay() instead. This is something Altera must investigate. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Clean up scc_mgr_zero_group()Marek Vasut2015-08-08-18/+21
| | | | | | | | First, zap unused argument of the function. Next, clean up the data types, constify where applicable, clean up comments and add kerneldoc. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Clean up scc_mgr_zero_all()Marek Vasut2015-08-08-8/+9

* ddr: altera: Extract scc_mgr_set_hhp_extras()Marek Vasut2015-08-08-4/+4
| | | | | | | | Move scc_mgr_set_hhp_extras() out of scc_set_bypass_mode() as it has nothing to do in there. Instead, invoke it from mem_calibrate() just before invoking scc_set_bypass_mode(). Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Clean up scc_mgr_set_hhp_extras()Marek Vasut2015-08-08-15/+22

* ddr: altera: Clean up scc_mgr_*_delay() argsMarek Vasut2015-08-08-18/+14

* ddr: altera: Clean up scc_mgr_load_dqs_for_write_group()Marek Vasut2015-08-08-11/+15

| * dm: core: Add a way to set a device nameSimon Glass2015-08-06-0/+10
| | | | | | | | | | | | | | | | | | | | Some devices are bound entirely by probing and do not have the benefit of a device tree to give them a name. This is very common with PCI and USB. In most cases this is fine, but we should add an official way to set a device name. This should be called in the device's bind() method.
