* arm: ls102xa: Add Freescale LS102xA SoC supportWang Huan2014-09-08-1/+7
| | | | | | | | | | | | | | | | | | The QorIQ LS1 family is built on Layerscape architecture, the industry's first software-aware, core-agnostic networking architecture to offer unprecedented efficiency and scale. Freescale LS102xA is a set of SoCs combines two ARM Cortex-A7 cores that have been optimized for high reliability and pack the highest level of integration available for sub-3 W embedded communications processors with Layerscape architecture and with a comprehensive enablement model focused on ease of programmability.

* ARM:asm:io.h use static inlineJeroen Hofstee2014-08-29-6/+6
| | | | | | | | | | | When compiling u-boot with W=1 the extern inline void for read* is likely causing the most noise. gcc / clang will warn there is never a actual declaration for these functions. Instead of declaring these extern make them static inline so it is actually declared. cc: Albert ARIBAUD <albert.u.boot@aribaud.net> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

| | | | | | | Previously the driver was only tested on Power SoCs. Different barrier instructions are needed for ARM SoCs. Signed-off-by: York Sun <yorksun@freescale.com>

* ARM: fix write*() I/O accessorsWolfgang Denk2011-02-21-3/+3
| | | | | | | | | | | | | | | | | | | Commit 3c0659b "ARM: Avoid compiler optimization for readb, writeb and friends." introduced I/O accessors with memory barriers. Unfortunately the new write*() accessors introduced a bug: The problem is that the argument "v" gets evaluated twice. This breaks code like used here (from "drivers/net/dnet.c"): for (i = 0; i < wrsz; i++) writel(*bufp++, &dnet->regs->TX_DATA_FIFO); Use auxiliary variables to avoid such problems.

* ARM: Avoid compiler optimization for readb, writeb and friends.Alexander Holler2011-02-02-12/+20
| | | | | | | | | | | | | | | | | | | | | gcc 4.5.1 seems to ignore (at least some) volatile definitions, avoid that as done in the kernel. Reading C99 6.7.3 8 and the comment 114) there, I think it is a bug of that gcc version to ignore the volatile type qualifier used e.g. in __arch_getl(). Anyway, using a definition as in the kernel headers avoids such optimizations when gcc 4.5.1 is used. Maybe the headers as used in the current linux-kernel should be used, but to avoid large changes, I've just added a small change to the current headers.

* Move architecture-specific includes to arch/$ARCH/include/asmPeter Tyser2010-04-13-0/+395
This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
