In the case that there was no name defined for a partition the
code assumes that name_len is 22 and therefore allocates exactly
that space for a dummy name. But the function sprintf() first
resolves "0x%08llx@0x%08llx" to a string that is longer than 22

mx25: fix the offset between the USB ports' registers
The USBOH module on imx25 chips contains two USB controllers which are
called USB OTG Controller and USB Host Controller. Each one has its EHCI
root hub. The OTG Controller's EHCI registers start at offset 0, the Host
Controller's registers start at offset 0x400.
We set CONFIG_MXC_USB_PORT=0 to select the OTG Controller and 1 for the
Host Controller. Therefore, IMX_USB_PORT_OFFSET must be 0x400. Using
this setting, the Host Controller starts working on my imx25 board.
Please note that the imx25 reference manual claims that the Host
Controller's registers start at 0x200. This is not correct. The Linux
Kernel uses the correct offset 0x400 in imx25.dtsi.

tools/imximage: get HAB information from header
Signing parts of a u-boot imximage for image verification in High
Assurance Boot (HAB) in a post-build process, requires some
information from the imximage header. Currently, this information is
only provided during the image build, which makes the transfer of this
information to the post-build process harder than necessary.
The i.MX HAB information (start and length) can be calculated either
by using information from the image-configuration file, or from the
information in the flash header of the imximage.
The advantage of using information from flash header is, that they are
not only available during image creation, but also available if
existing images are processed.

$ tools/mkimage -l u-boot.imx
