This is not true for recent Sitara SoCs:

I'm using the following partition layout (both working on eMMC and sdcard
with u-boot_2014.07.bb):

# fdisk -lu /dev/mmcblk0

Disk /dev/mmcblk0: 1920 MB, 1920991232 bytes, 3751936 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x00000000

        Device Boot      Start         End      Blocks   Id  System
/dev/mmcblk0p1   *          63       80324       40131    c  W95 FAT32 (LBA)
/dev/mmcblk0p2           80325     1558304      738990   83  Linux
/dev/mmcblk0p3         1558305     3036284      738990   83  Linux
/dev/mmcblk0p4         3036285     3743144      353430    5  Extended
/dev/mmcblk0p5         3036348     3068414       16033+  83  Linux
/dev/mmcblk0p6         3068478     3743144      337333+  83  Linux


With u-boot-ti-staging_2014.07.bb I just can boot from sdcard.
I'm using daisy branch, meta-linaro-toolchain with gcc 4.8.
