image.bbclass question

[Ryan Eatmon <reatmon@ti.com>]

I am trying to add support for the INITRAMFS_MAXSIZE into the meta-ti 
layer for our tiny image.

I have added the following to our tiny image file:

INITRAMFS_FSTYPES += "cpio cpio.xz"
INITRAMFS_MAXSIZE = "65536"

But I'm not seeing any errors about the image being too big being printed.

In looking at the code in question:

     # Check the initramfs size against INITRAMFS_MAXSIZE (if set)
     if image_fstypes == initramfs_fstypes != ''  and initramfs_maxsize:
         initramfs_maxsize_int = int(initramfs_maxsize)
         if base_size > initramfs_maxsize_int:
             bb.error("The initramfs size %d(K) exceeds 
INITRAMFS_MAXSIZE: %d(K)" % \
                 (base_size, initramfs_maxsize_int))
             bb.error("You can set INITRAMFS_MAXSIZE a larger value. 
Usually, it should")
             bb.fatal("be less than 1/2 of ram size, or you may fail to 
boot it.\n")


What is the purpose of the:

if image_fstypes == initramfs_fstypes != ''


It seems to looking for the ONLY images being built are the exact same 
as the INITRAMFS_FSTYPES...  Shouldn't that be more of an intersection 
check?  If any of the INITRAMFS_FSTYPES are in the IMAGE_FSTYPES, then 
check the size?

Or am I missing something?
