powerpc: macros for e500mc timer regs added

2014-08-01T21:18:07Z

For e500mc cores the watchdog timer period has to be set by means of a 6bit value, that defines the bit of the timebase counter used to signal a watchdog timer exception on its 0 to 1 transition. The macro used to set the watchdog period TCR_WP, was redefined for e500mc to support 6 WP setting. The parameter (x) given to the macro specifies the prescaling factor of the time base clock (fTB): watchdog_period = 1/fTB * 2^x Signed-off-by: Rainer Boschung Reviewed-by: York Sun

powerpc/mpc85xx: Removed support for G4060

powerpc: hiddendragon: remove orphan board

2014-05-30T18:03:24Z

This board has been orphan for a while. (Emails to its maintainer have been bouncing.) Because MPC82xx family is old enough, nobody would pick up the maintainership on it. Signed-off-by: Masahiro Yamada Cc: Wolfgang Denx

powerpc/mpc85xx: Added B4460 support

2014-05-16T21:24:26Z

B4460 differs from B4860 only in number of CPU cores, hence used existing support for B4860. B4460 has 2 PPC cores whereas B4860 has 4 PPC cores. Signed-off-by: Shaveta Leekha Signed-off-by: Sandeep Singh Signed-off-by: Poonam Aggrwal Reviewed-by: York Sun

powerpc/85xx: add T4080 SoC support

2014-05-13T15:26:54Z

The T4080 SoC is a low-power version of the T4160. T4080 combines 4 dual-threaded Power Architecture e6500 cores with single cluster and two memory complexes. Signed-off-by: Shengzhou Liu

powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260

2014-03-07T15:59:06Z

Before this commit, CONFIG_MPC8260 and CONFIG_8260 were used mixed-up. All boards with mpc8260 cpu defined both of them: - CONFIG_MPC8260 was defined in board config headers and include/common.h - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk We do not need to have both of them. This commit keeps only CONFIG_MPC8260. This commit does: - Delete CONFIG_8260 and CONFIG_MPC8260 definition in config headers and include/common.h - Rename CONFIG_8260 to CONFIG_MPC8260 in arch/powerpc/cpu/mpc8260/config.mk. - Rename #ifdef CONFIG_8260 to #ifdef CONFIG_MPC8260 Signed-off-by: Masahiro Yamada Cc: Wolfgang Denk

fsl_i2c: add workaround for the erratum I2C A004447

2013-08-20T09:15:31Z

This workaround is for the erratum I2C A004447. Device reference manual provides a scheme that allows the I2C master controller to generate nine SCL pulses, which enable an I2C slave device that held SDA low to release SDA. However, due to this erratum, this scheme no longer works. In addition, when I2C is used as a source of the PBL, the state machine is not able to recover. At the same time, delete the reduplicative definition of SVR_VER and SVR_REV. The SVR_REV is the low 8 bits rather than the low 16 bits of svr. And we use the CONFIG_SYS_FSL_A004447_SVR_REV macro instead of hard-code value 0x10, 0x11 and 0x20. The CONFIG_SYS_FSL_A004447_SVR_REV = 0x00 represents that one version of platform has this I2C errata. So enable this errata by IS_SVR_REV(svr, maj, min) function.
