The brand new devicetree nodes are introduced (intending to be a subset of the QuiccEngine-equipped models, with dts sources placed into the kernel according to the new convention. Assuming all the preceding stuff applied (PAL+fs_enet related+ CPM_UART update), the both TSEC eth ,FCC Eths, and both SCC UARTs are working. The relevant drivers are still capable to drive users in ppc, which was verified with 8272ADS (SCC uart+FCC eth). This is also verified on mpc8540 and actually make it work (PCI stuff working as well) Signed-off-by: Vitaly Bordug --- include/asm-powerpc/mpc85xx.h | 53 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 include/asm-powerpc/mpc85xx.h (limited to 'include/asm-powerpc') diff --git a/include/asm-powerpc/mpc85xx.h b/include/asm-powerpc/mpc85xx.h new file mode 100644 index 0000000..ccdb8a2 --- /dev/null +++ b/include/asm-powerpc/mpc85xx.h @@ -0,0 +1,53 @@ +/* + * include/asm-powerpc/mpc85xx.h + * + * MPC85xx definitions + * + * Maintainer: Kumar Gala + * + * Copyright 2004 Freescale Semiconductor, Inc + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License as published by the + * Free Software Foundation; either version 2 of the License, or (at your + * option) any later version. + */ + +#ifdef __KERNEL__ +#ifndef __ASM_MPC85xx_H__ +#define __ASM_MPC85xx_H__ + +#include + +#ifdef CONFIG_85xx + +#if defined(CONFIG_MPC8540_ADS) || defined(CONFIG_MPC8560_ADS) +#include +#endif +#if defined(CONFIG_MPC8555_CDS) || defined(CONFIG_MPC8548_CDS) +#include +#endif +#ifdef CONFIG_MPC85xx_CDS +#include +#endif + +#define _IO_BASE isa_io_base +#define _ISA_MEM_BASE isa_mem_base +#ifdef CONFIG_PCI +#define PCI_DRAM_OFFSET pci_dram_offset +#else +#define PCI_DRAM_OFFSET 0 +#endif + +/* Let modules/drivers get at CCSRBAR */ +extern phys_addr_t get_ccsrbar(void); + +#ifdef MODULE +#define CCSRBAR get_ccsrbar() +#else +#define CCSRBAR BOARD_CCSRBAR +#endif + +#endif /* CONFIG_85xx */ +#endif /* __ASM_MPC85xx_H__ */ +#endif /* __KERNEL__ */ -- cgit v1.1 From fc8e50e349aa722d9f97ed9ba30e324ede8fa408 Mon Sep 17 00:00:00 2001 From: Vitaly Bordug Date: Thu, 21 Sep 2006 22:37:58 +0400 Subject: POWERPC: Get rid of remapping the whole immr The stuff below cleans up the code attempting to remap the whole cpm2_immr early, as well as places happily assuming that fact. This is more like the 2.4 legacy stuff, and is at least confusing and unclear now. To keep the world comfortable, a new mechanism is introduced: before accessing specific immr register/register set, one needs to map it, using cpm2_map(), for instance, access to CPM command register will look like volatile cpm_cpm2_t *cp = cpm2_map(im_cpm); keeping the code clear, yet without "already defined somewhere" cpm2_immr. So far, unmapping code is not implemented, but it's not a big deal to add it, if the whole idea makes sense.

This abstracts rtc chip specific code from the platform code for rtc-over-i2c platforms. Specific RTC chip support is now configured under Device Drivers -> Real Time Clock. Setting time of day from the RTC on startup is also configurable. this time without the potentially platform breaking initcall.
