2008-12-15i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functionsTimur Tabi
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.

2008-12-10MIPS: Flush data cache upon relocationStefan Roese
This patch now adds a flush to the data cache upon relocation. The current implementation is missing this. Only a comment states that it should be done. So let's really do it now. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>
2008-12-10MIPS: Add CONFIG_SKIP_LOWLEVEL_INITStefan Roese
This patch adds the CONFIG_SKIP_LOWLEVEL_INIT option to start.S. This enables support for boards where the lowlevel initialization is already done when U-Boot runs (e.g. via OnChip ROM). This will be used in the upcoming VCTH board support. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp>

2008-12-0485xx: Fix relocation of CCSRBARKumar Gala
If the virtual address for CCSRBAR is the same after relocation but the physical address is changing we'd end up having two TLB entries with the same VA.

2008-11-21ppc4xx: Changed 460EX/GT OCM TLB and internal SRAM initializationDave Mitchell
Expanded OCM TLB to allow access to 64K OCM as well as 256K of internal SRAM. Adjusted internal SRAM initialization to match updated user manual recommendation. OCM & ISRAM are now mapped as follows: physical virtual size ISRAM 0x4_0000_0000 0xE300_0000 256k OCM 0x4_0004_0000 0xE304_0000 64k A single TLB was used for this mapping.

2008-11-21AT91: Enable PLLB for USBStelian Pop
At least some (old ?) versions of the AT91Bootstrap do not set up the PLLB correctly to 48 MHz in order to make USB host function correctly. This patch sets up the PLLB to the same values Linux uses, and makes USB work ok on the following CPUs: - AT91CAP9 - AT91SAM9260 - AT91SAM9263 This patch also defines CONFIG_USB_STORAGE and CONFIG_CMD_FAT for all the relevant AT91CAP9/AT91SAM9 atmel boards.

2008-11-10mpc8641: Support 36-bit physical addressingBecky Bruce
This patch creates a memory map with all the devices in 36-bit physical space, in addition to the 32-bit map. The CCSR relocation is moved (again, sorry) to allow for the physical address to be 36 bits - this requires translation to be enabled. With 36-bit physical addressing enabled, we are no longer running with VA=PA translations. This means we have to distinguish between the two in the config file. The existing region name is used to indicate the virtual address, and a _PHYS variety is created to represent the physical address. Large physical addressing is not enabled by default. Set CONFIG_PHYS_64BIT in the config file to turn this on. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-11-10mpc8641: Change 32-bit memory mapBecky Bruce
The memory map on the 8641hpcn is modified to look more like the 85xx boards; this is a step towards a more standardized layout going forward. As part of this change, we now relocate the flash. The regions for some of the mappings were far larger than they needed to be. I have reduced the mappings to match the actual sizes supported by the hardware. In addition I have removed the comments at the head of the BAT blocks in the config file, rather than updating them. These get horribly out of date, and it's a simple matter to look at the defines to see what they are set to since everything is right here in the same file. Documentation has been changed to reflect the new map, as this change is user visible, and affects the OS which runs post-uboot. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-11-10mpc86xx: Change early FLASH mapping to 1M at CONFIG_MONITOR_BASE_EARLYBecky Bruce
We define CONFIG_MONITOR_BASE_EARLY to define the initial location of the bootpage in flash. Use this to create an early mapping definition for the FLASH, and change the early_bats code to use this. This change facilitates the relocation of the flash since the early mappings are no longer tied to the final location of the flash. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-11-10mpc86xx: Use SRR0/1/rfi to enable address translation, not blrBecky Bruce
Using a mtmsr/blr means that you have to be executing at the same virtual address once you enable translation. This is unnecessarily restrictive, and is not really how this is usually done. Change it to use the more common mtspr SRR0/SRR1 and rfi method. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-11-10mpc86xx: Move setup_bats into cpu_init_fBecky Bruce
In order to later allow for a physical relocation of the flash, setup_bats, which sets up the final BAT mapping for the board, needs to happen *after* init_laws(). Otherwise, there will be no window programmed for the flash at the new physical location at the point when we change the mmu translation. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
