* ppc: Use r12 instead of r14 as GOT pointer.Joakim Tjernlund2010-01-26-5/+6
| | | | | | | | r14 is not supposed to be clobbered by functions. Switch to r12 and call GET_GOT when needed. This will allow u-boot to loose the -ffixed-r14 gcc option. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* ppc: Loose GOT access in IRQJoakim Tjernlund2010-01-26-33/+3
| | | | | | | | Using the GOT in IRQ handlers requires r14 to be -ffixed-r14. Avoid this by relocatate transfer_to_handler too. This will allow to free up r14 later on. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* kgdb: drop duplicate debugger_exception_handlerMike Frysinger2010-01-18-4/+0

* relocation: Do not relocate NULL pointers.Joakim Tjernlund2009-10-08-2/+4
| | | | | | | | | | NULL is an absolute value and should not be relocated. After this correction code like: void weak_fun(void) __attribute__((weak)); printf("weak_fun:%p\n", weak_fun); will still print null after relocation. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* 8xx serial, smc: add configurable SMC Rx buffer lenHeiko Schocher2009-02-11-37/+57
| | | | | | | | | | | | | | This patch adds the configuration option CONFIG_SYS_SMC_RXBUFLEN. With this option it is possible to allow the receive buffer for the SMC on 8xx to be greater then 1. In case CONFIG_SYS_SMC_RXBUFLEN == 1 this driver works as the old version. When defining CONFIG_SYS_SMC_RXBUFLEN also CONFIG_SYS_MAXIDLE must be defined to setup the maximum idle timeout for the SMC.

* i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functionsTimur Tabi2008-12-15-33/+0
| | | | | | | | | | All implementations of the functions i2c_reg_read() and i2c_reg_write() are identical. We can save space and simplify the code by converting these functions into inlines and putting them in i2c.h.

* PPC: Use r2 instead of r29 as global data pointerWolfgang Denk2008-02-14-1/+1
| | | | | | | | | | | | R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de>

* Fix and optimize MII operations on FEC (MPC8xx) controllersGuennadi Liakhovetski2008-01-09-54/+53
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes several issues at least on a MPC885 based system with two FEC interfaces used in MII mode. 1. PHY discovery should first read PHY_PHYIDR2 register and only then PHY_PHYIDR1 like cpu/mpc8xx/fec.c::mii_discover_phy() does it, otherwise the values read are wrong. Also notice, that PHY discovery cannot work on MPC88x / MPC87x in setups with both FECs active at all in its present form, because for both interfaces the registers from FEC 1 are used to communicate over MII. 2. Remove code duplication for resetting the FEC by isolating it into a separate function. 3. Initialize MII on FEC 1 when communicating over FEC 2 in fec_init(). 4. Optimize mii_init() to only reset the FEC 1 controller once. 5. Fix a typo in mii_init() using index i instead of j thus potentially leading to unpredictable results.

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-9/+13
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

* Bugfix in FEC initialisation:Markus Klotzbuecher2006-07-12-1/+3
| | | | | | | | All MII configuration is done via FEC1 registers. But MII_SPEED was configured according to FEC used. So if only FEC2 was used, this caused the real MII_SPEED register in FEC1 to stay uninitalised, what lead to "mii_send STUCK!" messages. Fix: always configure MII_SPEED on FEC1 only.
