As mentioned before Stefan discovered this working on Vybrid where we saw similar speed-up when booting from NAND flash.

I'll rebase u-boot-tegra/master against ARM master and apply this, and if no other Tegra patches are pending, I'll send a PR later this week. Thanks, Tom. According to my notes the following 10 patches are still pending: [PATCH] arm: tegra: use architecture specific memcpy Tested-by: Stephen Warren <swarren@nvidia.com> [PATCH v2] ARM: tegra: Use mem size from MC in combination with get_ram_size() Acked-by: Stephen Warren <swarren@nvidia.com> [PATCH] tegra: colibri_t30: clean-up spurious new line Acked-by: Simon Glass <sjg@chromium.org> [PATCH] tegra: gpio: fix null label regression Acked-by: Simon Glass <sjg@chromium.org> [PATCH] tegra: apalis_t30: master revamp [PATCH] tegra: dts: colibri_t30 add serial port details [PATCH] tegra: clean-up useless define Acked-by: Simon Glass <sjg@chromium.org> [PATCH] gpio: header file comment spelling fixes Acked-by: Simon Glass <sjg@chromium.org> [PATCH] tegra: colibri_t30: asix usb ethernet reset regression Acked-by: Simon Glass <sjg@chromium.org> [PATCH] mmc: Tegra: Fix timeout issue seen on certain eMMC parts Are you OK with those or should I resend any of them? BTW: Maybe acknowledging patch emails with applied messages like some other maintainers do would ease the tracking of an individual patch's status.
