* ARM: tegra: don't request GPIO from Seaboard's SPLStephen Warren2012-10-29-10/+4
| | | | | | | | | | | | | | | | Seaboard has a GPIO that switches an external mux between Tegra's debug UART and SPI flash. This is initialized from the SPL so that SPL debug output can be seen. Simplify the code that does this, and don't actually request the GPIO in the SPL; just program it. This saves ~4.5K from the size of the SPL, mostly BSS due to the large gpio_names[] table that is no longer required. This makes Seaboard's SPL fit within the current max size.

* ARM: tegra: select between Seaboard/Ventana at compile timeStephen Warren2012-10-29-3/+1
| | | | | | | | | | | | | | Seaboard and Ventana are very similar boards, and so share the seaboard.c board file. The one difference needed so far is detected at run-time by calling machine_is_ventana(). This bloats the Ventana build with code that is never used. Switch to detecting Ventana at compile time to remove bloat. This shaves ~5K off the SPL size on Ventana, and makes the SPL fit within the max size.

* ARM: tegra: derive CONFIG_SPL_MAX_SIZE instead of hard-coding itStephen Warren2012-10-29-1/+2
| | | | | | | | | | | | | | | For Tegra, the SPL and main U-Boot are concatenated together to form a single memory image. Hence, the maximum SPL size is the different in TEXT_BASE for SPL and main U-Boot. Instead of manually calculating SPL_MAX_SIZE based on those two TEXT_BASE, which can lead to errors if one TEXT_BASE is changed without updating SPL_MAX_SIZE, simply perform the calculation automatically.

* ARM: enhance u-boot.lds to detect over-sized SPLStephen Warren2012-10-29-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Add an ASSERT() to u-boot.lds to detect an SPL that doesn't fit within SPL_TEXT_BASE..SPL_MAX_SIZE. Different .lds files implement this check in two possible ways: 1) An ASSERT() like this 2) Defining a MEMORY region of size SPL_MAX_SIZE, and re-directing all linker output into that region. Since u-boot.lds is used for both SPL and main U-Boot, this would entail only sometimes defining a MEMORY region, and only sometimes performing that redirection, and hence option (1) was deemed much simpler, and hence implemented. Note that this causes build failures at least for NVIDIA Tegra Seaboard and Ventana. However, these are legitimate; the SPL doesn't fit within the required space, and this does cause runtime issues.

* ARM: tegra: Whistler: remove unused USB aliasStephen Warren2012-10-29-1/+4
| | | | | | | | | | | Port USB1 on Whistler is intended as a device port for USB recovery. Whistler's DT currently contains an alias for this USB port, even though Whistler's config doesn't enable multiple USB controllers, so the alias is unused. Remove the unused alias for consistency for now. Similar, explicitly disable the port in the device tree too.

* ARM: tegra: Seaboard: enable multiple USB portsStephen Warren2012-10-29-0/+1
| | | | | | | | | | | | | | | | The device tree already contains the required configuration for both the USB1 and USB3 ports. Enable the required configuration options to enable both these ports, which in turn allows the USB1 port to be used. Note that on a true Seaboard, this port is typically used as a device port hosting Tegra's USB recovery protocol. However, on the Springbank derivative, this port is the only external USB port, so we enable it as a host port so that USB peripherals may be used. Enabling this port in U-Boot as a host port doesn't prevent the port from reverting to a device port when the CPU is reset into recovery mode.

* ARM: tegra: use standard variables to define load addressesStephen Warren2012-10-29-3/+28
| | | | | | | | | | | | | | | | Currently, Tegra's default environment uses non-standard variables to define where boot scripts should load the kernel, FDT, and initrd. This change both changes the variable names to match those described in U-Boot's README, and shuffles their values around a little so that the values make a little more sense; see comments in the patch for rationale behind the values chosen. Note that this patch does remove the old non-standard variable "fdt_load" from the default environment, so this patch requires people to change their boot scripts.

* ARM: tegra: define CONFIG_SYS_BOOTMAPSZStephen Warren2012-10-29-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This define indicates the size of the memory region where it is safe to place data passed to the Linux kernel (ATAGs, DTB, initrd). The value needs to be: a) Less than or equal to RAM size. b) Small enough that the area is not within the kernel's highmem region, since the kernel cannot access ATAGs/DTB/initrd from highmem. c) Large enough to hold the kernel+DTB+initrd. 256M seems large enough for (c) in most circumstances, and small enough to satisfy (a) and (b) across any possible Tegra board. Note that the user can override this value via environment variable "bootm_mapsize" if needed. The advantage of defining BOOTMAPSZ is that we no longer need to define variable fdt_high in the default environment. Previously, we defined this to prevent the DTB from being relocated to the very end of RAM, which on most Tegra systems is within highmem, and hence which would cause boot failures. A user can still define this variable themselves if they want the FDT to be either left in-place wherever loaded, or copied to some other specific location. Similarly, there should no longer be a strict requirement for the user to define initrd_high if using an initrd.

| | | | | | | | | | | | | | | | | | | For Non-Nvidia boards to include newly added features (like emc clock scaling) it would be necessary to add each feature to their own board Makefile. This is because currently the top Makefile automaticly includes these features only for Nvidia boards. This patch adds a simple Makefile include so all new features become available for non-Nvidia board vendors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently PLL2 is not explicitely configured for mx53 and it runs at 333MHz. Since PLL2 is the parent clock for DDR2, IPU, VPU, we should set it at 400MHz instead. Without doing so, it is not possible to use a 2.6.35 FSL kernel and display HDMI at 1080p because the IPU clock cannot reach the requested frequency. Set PLL2 to 400MHz, so that 1080p can be played and the DDR2 can run at its maximum frequency. Also, setup the other PLL's as done in FSL U-boot and re-arrange the code a little bit to allow easier comparison with the original clock setup from FSL U-boot.
