* powerpc: Make ppc_md.{halt, restart} __noreturnDaniel Axtens2016-07-141-1/+1
| | | | | | | | | | | | powernv marks it's halt and restart calls as __noreturn. However, ppc_md does not have this annotation. Add the annotation to ppc_md, and then to every halt/restart function that is missing it. Additionally, I have verified that all of these functions do not return. Occasionally I have added a spin loop to be sure. Signed-off-by: Daniel Axtens <dja@axtens.net> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
* powerpc/mpc512x: add MPC5125 reset module support for system restartMatteo Facchinetti2013-06-241-0/+1
| | | | | | | | | | | | | | | Only part of MPC5125 reset module is like as MPC5121. In detail, RCWH register doesn't contain informations about: - PCI arbiter - NAND flash page size - NAND flash port size For this reason, in device tree, this module has a different name then MPC5121 reset module but use the same "struct mpc512x_reset_module" register definition and the same restart procedure.

* powerpc/mpc512x: move common code to shared.c fileGerhard Sittig2013-05-211-9/+2
| | | | | | | | | | | | | | | | | - implement all of the init, init early, and setup arch routines in the shared source file for the MPC512x PowerPC platform, and make all MPC512x based boards (ADS, PDM, generic) use those common routines - remove declarations from header files for routines which aren't referenced from external callers any longer this modification concentrates knowledge about the optional FSL DIU support in one spot within the shared code, and makes all boards benefit transparently from future improvements in the shared platform code the change does not modify any behaviour but preserves all code paths Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de>
* powerpc/mpc512x: add platform code for MPC5125.Matteo Facchinetti2013-04-101-0/+1
| | | | | | | | | | | | | | | Tested on MPC5125 Tower evaluation board with mpc512x_defconfig compile configuration. In detail, supports for: - PSC / UART - RTC - ETH - DIU - I2C Signed-off-by: Matteo Facchinetti <matteo.facchinetti@sirius-es.it> Signed-off-by: Anatolij Gustschin <agust@denx.de>
* powerpc/512x: don't compile any platform DIU code if the DIU is not enabledTimur Tabi2012-12-031-2/+9
| | | | | | | | | | | | | | | | | If the DIU framebuffer driver is not enabled, then there's no point in compiling any platform DIU code, because it will never be used. Most of the platform code was protected in the appropriate #ifdef, but not all. This caused a break in some randconfig builds. This is only a problem on the 512x platforms. The P1022DS and MPC8610HPCD platforms are already correct. This patch reverts commit 12e36309f8774f4ccc769d5e3ff11ef092e524bc ("powerpc: Option FB_FSL_DIU is not really optional for mpc512x") and restores the ability to configure DIU support.

* powerpc/5121: shared DIU framebuffer supportAnatolij Gustschin2010-08-011-0/+2
| | | | | | | | | | | | | | | | | | | MPC5121 DIU configuration/setup as initialized by the boot loader currently will get lost while booting Linux. As a result displaying the boot splash is not possible through the boot process. To prevent this we reserve configured DIU frame buffer address range while booting and preserve AOI descriptor and gamma table so that DIU continues displaying through the whole boot process. On first open from user space DIU frame buffer driver releases the reserved frame buffer area and continues to operate as usual.

* powerpc/mpc5121: avoid using arch_initcall for clock initAnatolij Gustschin2010-02-161-0/+2
| | | | | | | | Move mpc5121_clk_init() call to platform init code so it won't get called on non-5121 platforms on a multiplatform kernel. Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* powerpc/5xxx: Add common mpc5xxx_get_bus_frequency() functionWolfgang Denk2009-06-171-1/+0
| | | | | | | | | | | So far, MPC512x used mpc512x_find_ips_freq() to get the bus frequency, while MPC52xx used mpc52xx_find_ipb_freq(). Despite the different clock names (IPS vs. IPB) the code was identical. Use common code for both processor families.
