powerpc/mpc85xx: Add DSP side awareness for Freescale Heterogeneous SoCs

2015-03-04T18:15:29+00:00

The code provides framework for heterogeneous multicore chips based on StarCore
and Power Architecture which are chasis-2 compliant, like B4860 and B4420

It will make u-boot recognize all non-ppc cores and peripherals like
SC3900/DSP CPUs, MAPLE, CPRI and print their configuration in u-boot logs.
Example boot logs of B4860QDS:

U-Boot 2015.01-00232-geef6e36-dirty (Jan 19 2015 - 11:58:45)

CPU0:  B4860E, Version: 2.2, (0x86880022)
Core:  e6500, Version: 2.0, (0x80400120)
Clock Configuration:
       CPU0:1600 MHz, CPU1:1600 MHz, CPU2:1600 MHz, CPU3:1600 MHz,
       DSP CPU0:1200 MHz, DSP CPU1:1200 MHz, DSP CPU2:1200 MHz, DSP CPU3:1200 MHz,
       DSP CPU4:1200 MHz, DSP CPU5:1200 MHz,
       CCB:666.667 MHz,

       FMAN1: 666.667 MHz
       QMAN:  333.333 MHz

Top level changes include:
(1) Top level CONFIG to identify HETEROGENUOUS clusters
(2) CONFIGS for SC3900/DSP components
(3) Global structures like "cpu_type" and "MPC85xx_SYS_INFO"
    updated for dsp cores and other components
(3) APIs to get DSP num cores and their Mask like:
        cpu_dsp_mask, cpu_num_dspcores etc same as that of PowerPC
(5) Code to fetch and print SC cores and other heterogenous
    device's frequencies
(6) README added for the same

common/board_f: factor out reserve_stacks

2015-02-17T21:52:42+00:00

Introduce arch_reserve_stacks() to tailor gd->start_addr_sp and gd->irq_sp to

generic-board: show model name in board_init_f() too

2015-01-30T00:09:49+00:00

The common/board_r.c has show_model_r() to display the model name
if the DTB has a "model" property.  It sounds useful to have a similar
function in common/board_f.c too because most of the boards show
their board name before relocation.

Instead of implementing the same function in both common/board_f.c
and common/board_r.c, let's split it up into common/show_board_info.c.

ARM: remove redundant asmlinkage define

2014-12-15T14:22:56+00:00

Use asmlinkage defined in include/linux/linkage.h if necessary.
Actually no ARM board uses asmlinkage, so this commit has no impact.

x86: move arch-specific asmlinkage to

2014-12-15T14:22:53+00:00

Commit 65dd74a674d6 (x86: ivybridge: Implement SDRAM init) introduced
x86-specific asmlinkage into arch/x86/include/asm/config.h.

Commit ed0a2fbf14f7 (x86: Add a definition of asmlinkage) added the
same macro define again, this time, into include/common.h.
(Please do not add arch-specific stuff to include/common.h any more;
it is already too cluttered.)

The generic asmlinkage is defined in .  If you want
to override it with an arch-specific one, the best way is to add it
to  like Linux Kernel.

powerpc: mpc8xx: remove hermes board support

2014-12-08T14:35:43+00:00

This board sprinkles #ifdef(CONFIG_HERMES) over various global files
such as include/common.h, common/board_r.c, common/cmd_bdinfo.c.
Let's zap such an ill-behaved board.

It has not been converted to generic board yet and mpc8xx is old
enough.
