* | | Respect memreserve regions specified in the device treeGrant Likely2011-04-25-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | If a regions is reserved in the fdt, then it should not be used. Add the memreserve regions to the lmb so that u-boot doesn't use them to store the initrd. Signed-off-by: Grant Likely <grant.likely@linaro.org>
* | | Remove device tree booting dependency on CONFIG_SYS_BOOTMAPSZGrant Likely2011-04-25-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The previous patch makes u-boot use the full accessible size of ram as the default boot mapped size if CONFIG_SYS_BOOTMAPSZ is not defined, which means boot_relocate_fdt() can be changed to depend solely on CONFIG_OF_LIBFDT.

* | | Default to bootm_size() when CONFIG_SYS_BOOTMAPSZ is not definedGrant Likely2011-04-25-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a function getenv_bootm_mapsize() for obtaining the size of the early mapped region accessible by the kernel during early boot. It defaults to CONFIG_SYS_BOOTMAPSZ, or if not defined, defaults to getenv_bootm_size(), which in turn defaults to the size of RAM. getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize" environmental variable.

* | | Stop passing around bootmem_base value.Grant Likely2011-04-25-13/+6
|/ / | | | | | | | | | | | | | | | | | | For the calls to boot_relocate_fdt(), boot_get_cmdline(), and boot_get_kbd(), the value of bootmem_base is always obtained by calling getenv_bootm_low(). Since the value always comes from the same source, the calling signature for those functions can be simplified by making them call getenv_bootm_low() directly.

| * | fsl: Change fsl_phy_enet_if to phy_interface_tAndy Fleming2011-04-20-35/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum. This meant that drivers which used fsl_phy_enet_if to deal with PHY interfaces would have to convert between the two (or we would have to have them mirror each other, and deal with the ensuing maintenance headache). Instead, we switch all clients of fsl_phy_enet_if over to phy_interface_t, which should become the standard, anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Blackfin gpio command isn't terribly Blackfin-specific. So generalize the few pieces into two new optional helpers: name_to_gpio() - turn a string name into a GPIO # gpio_status() - display current pin bindings (think /proc/gpio) Once these pieces are pulled out, we can relocate the cmd_gpio.c into the common directory.

Since caches need CPLBs and CPLBs need exception handlers, but we're about to rewrite the code in memory where those exception handlers live, we need to turn off caches first.

Since all of the inputs to this are 32-bit (nanoseconds, clock cycles, and DDR frequencies), we can easily restructure the computation to use the "do_div()" function to perform 64-bit/32-bit divide operations. On 64-bit this change is basically a no-op, because do_div is implemented as a literal 64-bit divide operation and the instruction scheduling works out almost the same. On 32-bit PowerPC a fully accurate 64/64 divide (__udivdi3 in libgcc) is over 1.1kB of code and thousands of heavily dependent cycles to compute, all of which is linked from libgcc. Another 1.2kB of code comes in for the function __umoddi3. It should be noted that nothing else in U-Boot or the Linux kernel seems to require a full 64-bit divide on my 32-bit PowerPC.
