Sudan MTDNA
Find below relative frequencies for Sudanese MTDNA from a thesis entitled "Genetic Patterns of Y-chromosome and Mitochondrial DNA Variation, with Implications to the Peopling of the Sudan", the entire thesis can be downloaded from here. The thesis also includes YDNA data, but those same results have been already covered in this blog post. Additionally, some interesting ancient YDNA data is also included in the thesis.
Note, I wrote a small script that can enable sorting of the relative frequencies by clicking the haplogroups, you can find the script@ JSFiddle, if you find the script useful and would like to use it for other relative frequency charts, please cite the JSFiddle link from above.

More East African mtDNA Charts
Below are more East African mtDNA bar graphs from the Hirbo Thesis, the complementary YDNA charts can be seen in this post, along with the Boattini paper featured here, this gives us a more complete picture of East African mtDNA with a reasonable amount of detail.
Google Visualization API has been having problems for the past couple of months, so the tool tips as well as other functionalities of Google charts may not work, this post will be updated if they fix some of these issues.
With respect to some of the data points, the populations labeled with a * had their total number of samples adjusted in order for the percentages shown in Table 3.4.1 to make sense, that is, Orma has been adjusted from 20 to 21, Marakwet from 22 to 23, Pokot from 39 to 38, San from 11 to 12 and Bamoun from 18 to 20.

Sudan YDNA
This is from a relatively old study, but it seems that it is the most comprehensive YDNA breakdown we have of North and South Sudan to date.
Y-chromosome variation among Sudanese: restricted gene flow, concordance with language, geography, and history. Hassan (2008)
Here is a map of the populations tested from Fig.1 of the Study
Here below is the phylogeny (as known back in 2008) of the SNPs tested, note that those in bold; E-M75, E-P2, G-M201 and T-M70 were NOT tested in the study.
The E-M78+ cases from above were also tested for Cruciani's V-Series SNPs as well for further resolution,
Some notes:

Some notes:
- The high level (38%) of E-M215 (x M78) in the Borgu is quite intriguing, I wonder what variant/s of E-M215 it is?
- Almost all the J-12f2(x M172) should be J-M267.
- B-M60 is found in Southern Nilo-Saharan speakers and not the North Western ones, while A-M13 is found in both.
- The
F-M89(x M52, M170, I2f2, M9) found in the north is also interesting, although it could possibly be G-M201, at least part of it. E-V22 has a relatively high presence in these samples, even when compared to the Egyptian samples from Cruciani '07, and most certainly higher than its presence in Ethiopia. The High presence of E-V12 (x V32) is also concordant with its putative area of origin, all the E-M78 found in the Nuer and the Copts is of this variety. The presence of E-M78* in the Masalit and the Nuba is notable. Off course the strangest result is the 54% R-M173 (x P25) in the Fulani, this could be some R1b*(R-M343), or some type of R1a, the latter would be very out of place for the region, while the former could be reconciled with the presence of more downstream R1b variants in Africa.

A speculative superimposition of E-M35 variants onto Afroasiatic.
Here is a speculative superimposition of the variants of YDNA E-M215/M35 (E1b1b/1) onto an Afroasiatic internal classification, Lionel Bender's (1997) classification.
The red question marks represent a less unsure fit.
